Scott Armstrong is a former Assistant Chief at the Department of Justice's Fraud Section and an accomplished federal trial lawyer who has tried sixteen complex cases in federal courts around the country. Scott is based in Washington, D.C. and defends individuals nationwide in federal court.
At Armstrong & Bradylyons PLLC, Scott defends executives, financial professionals, and medical professionals facing complex white-collar investigations and charges. He provides creative and tenacious defenses in cases involving allegations of healthcare fraud, cryptocurrency and digital asset fraud, securities fraud, insider trading, market manipulation, computer fraud, procurement fraud, FCPA violations, bank fraud, and money laundering.
Scott also represents companies and individuals in high-stakes business disputes and civil litigation involving fraud and related misconduct. His first-chair experience in complex federal cases also makes him a valuable trial partner for other attorneys navigating high-stakes matters through trial.
Scott defends licensed medical professionals, including physicians, nurses, pharmacists, and healthcare executives, against criminal and civil healthcare fraud charges and regulatory investigations. At DOJ's Fraud Section, Scott served as lead counsel in healthcare fraud cases totaling over $600 million in false and fraudulent claims involving Medicare, Medicaid, Tricare, and other federal programs. He also served as Director of DOJ's Appalachian Regional Prescription Drug Task Force.
Scott now defends clients against allegations of healthcare fraud (18 U.S.C. § 1347), wire fraud (18 U.S.C. § 1343), violations of the Anti-Kickback Statute (42 U.S.C. § 1320a-7b), major fraud against the United States (18 U.S.C. § 1031), false statements relating to a healthcare matter (18 U.S.C. § 1035), diversion of controlled substances (21 U.S.C. § 841), and conspiracy to commit healthcare fraud (18 U.S.C. §§ 371, 1349).
His healthcare fraud defense practice protects medical professionals against allegations of wound care fraud, home health services fraud, durable medical equipment (DME) fraud, Medicare Part B and Medicare Advantage fraud, laboratory and genetic testing fraud, telemedicine and telehealth fraud, compounding pharmacy fraud, behavioral health and substance abuse treatment fraud, injection and infusion therapy fraud, and controlled substances diversion and illegal prescribing.
Scott defends medical professionals in investigations and prosecutions brought by the Strike Forces of DOJ's Fraud Section, Healthcare Fraud Unit; United States Attorneys' Offices around the country; the Department of Health and Human Services, Office of Inspector General (HHS-OIG); the FBI; the Drug Enforcement Administration (DEA); the Food and Drug Administration, Office of Criminal Investigations (FDA-OCI); the Centers for Medicare and Medicaid Services (CMS); state Medicaid Fraud Control Units (MFCUs); and state medical and professional licensing boards.
Scott has tried healthcare fraud and anti-kickback statute cases involving approximately one hundred million dollars in false claims. He knows how federal prosecutors build cases by analyzing claims data, dissecting complex patient files, obtaining and using electronic communications, and relying on witness testimony. He uses that experience to challenge the government's theories of medical necessity, identify weaknesses in claims-data analysis, and dismantle allegations of kickback arrangements at every stage of an investigation. And if a case cannot be resolved on favorable terms, Scott has the first-chair trial experience to defend medical professionals at trial in federal court.
Scott defends protocol founders, traders, marketers, and DeFi developers against allegations of cryptocurrency fraud, digital-asset misappropriation, market manipulation, and money laundering.
At DOJ's Fraud Section, Scott supervised and led a team of federal prosecutors investigating and trying nationwide high-profile cryptocurrency cases, including cases involving multi-million-dollar crypto Ponzi schemes, NFT rug pulls, pig butchering or affinity schemes involving international actors, cherry picking schemes involving registered advisors and cryptocurrency futures, and investment-fraud schemes involving former registered brokers. Scott also tried the first-ever cryptocurrency manipulation case under Title 15 in the Southern District of Florida that involved over $300 million in manipulation through spoof orders and wash trades.
In addition to his trial experience with crypto cases, Scott draws on his deep experience in DeFi protocols, blockchain technology, and wallet tracing to defend and counsel clients across every corner of the cryptocurrency market. He defends clients against charges of wire fraud (18 U.S.C. § 1343), conspiracy to commit wire fraud (18 U.S.C. § 1349), money laundering (18 U.S.C. §§ 1956, 1957), and conspiracy to commit money laundering (18 U.S.C. §§ 1349, 1956(h)). These cases involve defense of individuals against charges brought by components of DOJ and United States Attorneys' Offices nationwide, as well as civil charges levied by the New York Attorney General (NYAG), other state attorneys general offices, and state securities regulators.
Scott also specifically defends individuals facing money laundering charges involving the use of mixing and tumbling services, chain-hopping across multiple blockchains, layering funds through decentralized and off-shore centralized exchanges, transacting in privacy coins, and using peer-to-peer platforms to convert crypto to fiat. Scott's experience in this space allows him to defend individuals by identifying any errors or weaknesses in the government's theory, proof, and admissible evidence.
Scott also defends individuals under investigation and indictment for ransomware attacks, computer fraud, SIM swap attacks, identity theft, and social engineering exploits involving cryptocurrency.
Scott defends executives, traders, financial advisors, accountants, broker-dealers, hedge fund managers, and investment professionals against allegations of fraud and manipulation in the financial markets. Scott defends these professionals based on his proven trial skills in federal court, familiarity with the capital markets, and skill with navigating complex trading data and messaging platforms.
As an Assistant Chief and senior supervisor at DOJ's Fraud Section, Scott tried and supervised complex multi-million-dollar fraud cases in federal courts across the country. These federal jury trials involved Ponzi schemes involving hundreds of millions of dollars laundered through financial institutions, market manipulation schemes involving over $300 million in spoof and wash trades, and a commodities fraud scheme involving precious metals futures contracts that was orchestrated by two senior traders at a major financial institution. Scott also supervised insider trading cases involving corporate board members and executives.
Scott has first-chair experience in fraud and manipulation cases across a range of financial products, including U.S. Treasuries, cryptocurrencies, futures, equities, and private investments. He defends clients against allegations of wire fraud (18 U.S.C. § 1343), securities fraud (15 U.S.C. § 78j(b) and SEC Rule 10b-5), commodities fraud (18 U.S.C. § 1348), insider trading (15 U.S.C. §§ 78j(b) and 78ff), market manipulation (15 U.S.C. § 78i(a)(2)), spoofing in the commodities markets (7 U.S.C. § 9(a)(2)), and conspiracy to commit securities or commodities fraud (18 U.S.C. §§ 371, 1349).
Scott defends clients in matters brought by DOJ's Fraud Section and other components; U.S. Attorney's Offices nationwide; the Securities and Exchange Commission (SEC); the Commodity Futures Trading Commission (CFTC); the Financial Industry Regulatory Authority (FINRA); the New York State Attorney General (NYAG); and state securities regulators.
Scott has tried securities and commodities fraud cases. He knows how federal prosecutors use trading data, chat logs, and electronic communications to build fraud cases. He uses that experience to find the weaknesses in the government's case and challenge its theories at every stage of an investigation. And if a case cannot be resolved on favorable terms, Scott has the trial skills and first-chair experience to defend his clients at trial in federal court.
Scott represents clients in complex disputes involving digital assets, blockchain technology, and crypto investments. Scott handles both offensive and defensive cryptocurrency litigation. Scott prosecutes claims for his clients to recover lost or misappropriated cryptocurrency and investment losses. He also defends clients' digital assets against government and third-party freeze orders, asset seizure, and civil and criminal forfeiture proceedings.
Scott has particular experience in smart contract disputes and navigating the complex technical and legal challenges of recovering digital assets that have become inaccessible through failed, exploited, or disputed smart-contract executions.
Scott also defends clients against Temporary Restraining Orders (TROs) seeking to freeze crypto wallets, digital asset holdings, and accounts at centralized exchanges, as well as clawback and disgorgement actions brought by federal receivers in CFTC and SEC enforcement cases.
Scott brings his trial-oriented approach and federal-prosecutor experience to crypto and digital asset disputes involving DeFi protocols, centralized and decentralized exchanges, tokenized assets and securities, stablecoins, and cross-chain transactions. His familiarity with blockchain technology, on-chain tracing, and the evolving federal regulatory landscape, including guidance and rules from DOJ, the SEC, the CFTC, and FinCEN, allows him to aggressively defend his clients' interests in cryptocurrency and digital asset disputes.
Crypto and digital asset disputes are complex, fast-moving, and high-stakes. Scott has the federal trial experience, technical background, and prosecutorial background to navigate these disputes from their earliest stages. And if a dispute cannot be resolved favorably, Scott has the first-chair trial skills to see a case through trial in federal court.
Scott defends healthcare providers, government contractors, and executives against False Claims Act (31 U.S.C. §§ 3729–3733) investigations, qui tam whistleblower lawsuits, and procurement fraud allegations.
Scott represents clients at every stage of an FCA enforcement case. He defends clients responding to Civil Investigative Demands (CIDs), during the sealed phase of qui tam actions, through DOJ intervention decisions, in settlement negotiations, and at trial if necessary. Because FCA investigations often carry parallel criminal exposure and collateral consequences, such as OIG exclusion or debarment from federal programs, Scott draws on his near decade-long tenure at DOJ's Fraud Section to defend clients across the full spectrum of civil, criminal, and administrative proceedings.
Scott's healthcare FCA defense practice is built on his experience as lead counsel in criminal healthcare fraud cases at DOJ involving over $600 million in false and fraudulent claims. He defends healthcare providers and executives against FCA allegations of upcoding, billing for medically unnecessary services, and Anti-Kickback Statute (42 U.S.C. § 1320a-7b) violations across wound care, home health, telehealth, pharmacy, laboratory testing, and Medicare Part B services.
Scott's procurement fraud defense practice covers bid-rigging, cost-mischarging, defective pricing, product substitution, and fraud involving Small Business Administration (SBA) programs. He defends government contractors and executives in investigations and cases brought by the Defense Criminal Investigative Service (DCIS), the FBI, the Department of Health and Human Services Office of Inspector General (HHS-OIG), the Small Business Administration Office of Inspector General (SBA-OIG), federal Inspectors General, and United States Attorney's Offices nationwide.
Scott knows how the government seeks to build FCA cases because he did just that at the Fraud Section for nearly a decade. He uses that experience to challenge the government's theories of liability, defend against inflated damages calculations, and protect his clients across parallel civil, criminal, and administrative proceedings.
Scott defends executives, business owners, and individuals in white-collar investigations and prosecutions brought by the Department of Justice and United States Attorneys' Offices nationwide. His practice spans the full range of federal criminal exposure, including violations of the Foreign Corrupt Practices Act (FCPA) (15 U.S.C. §§ 78dd-1 et seq.), bank fraud (18 U.S.C. § 1344), mortgage fraud, false statements (18 U.S.C. § 1001, 1014), theft of government property (18 U.S.C. § 641), and aggravated identity theft (18 U.S.C. § 1028A).
Many of these matters begin long before charges are filed. Scott represents clients at the earliest stages of an investigation, whether they receive a grand jury subpoena, a target letter, or an unannounced visit from federal agents. He works to shape the government's understanding of the facts, protect his clients' interests during interviews and proffers, and position each case for declination, favorable resolution, or trial.
Scott represents businesses, executives, and individuals in high-stakes disputes and complex civil litigation in federal courts nationwide. He handles breach of contract and breach of fiduciary duty claims, business fraud and conversion actions, and investment disputes involving allegations of fraudulent inducement, constructive fraud, and unjust enrichment.
Scott litigates business disputes in the same heavily regulated industries where he defends clients in criminal and FCA matters. These include healthcare, financial services, government contracting, and digital assets. These cases demand fluency in federal regulations, compliance frameworks, and industry-specific standards. Scott spent nearly a decade navigating these regulatory environments as a federal prosecutor at DOJ's Fraud Section. That federal prosecutor experience allows him to litigate civil disputes where the subject matter is as complex as the legal claims.
Scott's experience at DOJ building and trying complex fraud cases translates directly to civil litigation. He knows how to develop case theories. He knows how to take and defend depositions, manage discovery in document-intensive matters, and present evidence to a jury. He brings that same investigative rigor and trial discipline to every civil matter he handles.
Scott also draws on his experience with complex financial data, electronic communications, and blockchain technology. He represents clients in disputes involving venture capital investments, private equity transactions, startup equity and compensation disputes, and joint ventures where fraud or misconduct is at the center of the case.
Scott approaches every civil dispute with trial preparation as the baseline. That posture strengthens every phase of a case. It positions clients for the strongest possible outcome, whether through early resolution, dispositive motion, or verdict. And if a case needs to proceed to trial, Scott has the first-chair experience to see it through.
Before joining the Department of Justice, Scott worked at an international law firm in Washington, D.C., where he defended individuals at trial, including an in-house attorney acquitted of obstruction charges, a former Blackwater security guard tried over ten weeks for his role during a shootout in Iraq, and an executive acquitted of charges relating to the BP oil spill.

What Is Scott Armstrong’s Background as a Federal Prosecutor?
Scott Armstrong is a former Assistant Chief at DOJ’s Fraud Section. He served for nearly a decade in the Criminal Division. His roles included Assistant Chief and senior supervisor in the Market Integrity and Major Fraud Unit, Director of DOJ’s Appalachian Regional Prescription Opioid Strike Force, and Trial Attorney in the Healthcare Fraud Unit.
Scott has tried sixteen complex federal cases around the country. These included multi-week, multi-defendant jury trials involving Ponzi schemes, market manipulation, commodities fraud, healthcare fraud, anti-kickback statute violations, opioid diversion, and cryptocurrency manipulation. He also supervised teams of federal prosecutors handling complex, multi-defendant financial fraud investigations nationwide.
Scott now uses that experience as a founding partner of Armstrong & Bradylyons PLLC to defend individuals and companies nationwide in federal criminal investigations, grand jury proceedings, regulatory enforcement actions, and high-stakes litigation. His DOJ tenure provides direct insight into how federal prosecutors build, charge, and try complex fraud cases—and where those cases break down.
What Types of Federal Cases Does Scott Armstrong Defend?
Scott defends individuals and companies nationwide across the full range of federal white-collar criminal matters. His defense practice covers healthcare fraud and anti-kickback statute violations, cryptocurrency fraud and money laundering, securities fraud, commodities fraud, and insider trading, False Claims Act and procurement fraud, FCPA and foreign corruption investigations, DEA enforcement actions against prescribers, and cybercrime allegations including SIM swaps, ransomware, and computer fraud.
Recent representations include executives in DOJ investigations of Medicare skin-substitute claims, a foreign national indicted in a $260 million crypto “social engineering” heist, a former executive in an FCPA investigation involving mineral exports from Africa, a member of a Congressional Committee in an insider-trading inquiry, and executives facing SEC, CFTC, FINRA, and state attorney general investigations.
Scott also represents businesses, executives, and individuals in complex civil litigation, cryptocurrency litigation, and digital asset recovery in federal courts nationwide. Every matter is built on his nearly decade-long tenure at DOJ’s Fraud Section trying and supervising complex fraud cases.
What Is Scott Armstrong’s Experience with Cryptocurrency Fraud and Crypto Money Laundering Defense?
Scott has first-chair federal trial experience in cryptocurrency cases on both sides of the “v.” At DOJ’s Fraud Section, he served as lead trial counsel in the first-ever trial conviction for conspiracy to commit securities price manipulation under Title 15 of the United States Code involving cryptocurrency—a case involving over $300 million in spoof orders and wash trades placed through an automated trading bot. He also served as lead counsel in the first-ever criminal “cherry-picking” prosecution of a Commodity Trading Advisor involving cryptocurrency futures.
In private practice, Scott defends the full spectrum of crypto enforcement matters. Representative engagements include: a foreign national indicted for conspiracy to commit wire fraud and money laundering in an alleged $260 million social engineering crypto heist; an individual in a DOJ investigation into an alleged ring conducting SIM swaps, ransomware attacks, and computer fraud; a cryptocurrency mining and lending protocol and its CEO in a DOJ investment fraud investigation; executives of a leading DeFi token and mining operation in an SEC investigation into asset misappropriation; a DeFi protocol founder in a New York Attorney General investigation into unregistered securities; and a marketer in a Maryland Attorney General investigation into cryptocurrency token practices.
Scott pairs this enforcement experience with deep familiarity with blockchain technology, DeFi protocols, and on-chain tracing. That combination allows him to challenge the government’s tracing methodology, intent evidence, and legal theories at every stage of a crypto fraud or crypto money laundering case.
What Is Scott Armstrong’s Experience with Healthcare Fraud Defense?
Scott defends physicians, nurse practitioners, physician assistants, pharmacists, healthcare executives, and startup founders nationwide against federal healthcare fraud charges, DOJ investigations, and regulatory enforcement. At DOJ’s Fraud Section, Scott served as lead trial counsel in healthcare fraud cases totaling over $600 million in false and fraudulent claims to Medicare, Medicaid, and Tricare, and directed DOJ’s Appalachian Regional Prescription Opioid Strike Force.
His DOJ trial record includes: lead counsel in a $126 million compounded-medication fraud scheme involving physicians, pharmacists, executives, and marketers; lead trial counsel in the Fraud Section’s first-ever use of data analytics to investigate and try a physician and clinic owner for conspiring to unlawfully dispense over 2 million opioid pills; and lead trial counsel in $26 million and $20 million kickback-driven medical necessity schemes, each resulting in convictions after week-long trials.
In private practice, representative matters include: founders and executives in DOJ investigations of Medicare claims for skin substitutes, including one investigation involving approximately $50 million in claims; executives of a leading peptides distributor in a DOJ investigation of “research use only” representations; executives in a DOJ and FDA-OCI investigation of a leading pharmaceutical company; a CEO in a DOJ wound care investigation; insurance broker executives in a DOJ investigation of representations to beneficiaries; and cardiologists against a False Claims Act complaint involving radiopharmaceutical claims tied to nuclear stress testing. Scott knows how prosecutors analyze claims data and build cases through cooperators—and he builds a trial-ready defense from day one.
Does Scott Armstrong Defend DEA Enforcement Actions and Controlled Substances Cases?
Yes. Scott defends physicians, nurse practitioners, physician assistants, and clinics in DEA administrative enforcement actions and federal controlled substances investigations. Representative matters include defending a nurse practitioner against a DEA Order to Show Cause and a physician assistant against a DEA Immediate Suspension Order, each arising from prescribing at a leading national testosterone clinic.
Scott’s controlled substances experience runs deeper than most defense attorneys’. He directed DOJ’s Appalachian Regional Prescription Opioid Strike Force and served as lead trial counsel in the Fraud Section’s first data-analytics-driven opioid prosecution, trying a physician and clinic owner for conspiring to unlawfully dispense over 2 million opioid pills. He knows precisely how DEA and DOJ use prescribing data, PDMP records, and expert testimony to build diversion cases against prescribers.
He uses that insight to defend registrants’ DEA registrations, respond to administrative subpoenas, and resolve parallel criminal exposure before charges are filed.
What Is Scott Armstrong’s Experience with Securities Fraud, Insider Trading, and Market Manipulation Defense?
Scott defends executives, traders, financial advisors, broker-dealers, and fund managers in federal securities fraud, commodities fraud, insider trading, and market manipulation investigations and prosecutions. He has first-chair experience across U.S. Treasuries, cryptocurrencies, futures, equities, and private investments.
At DOJ, Scott served as co-lead trial counsel against two senior traders at a major bank, convicted after a two-week trial for a years-long manipulation scheme in the precious metals futures markets. He served as lead trial counsel in a two-week trial convicting two defendants of a Ponzi scheme that laundered approximately $650 million through financial institutions, and co-led the investigation of a FINRA-registered broker who pleaded guilty to defrauding investors in a private cryptocurrency fund.
In private practice, representative matters include: a member of a Congressional Committee in an insider-trading inquiry; an individual in an SEC insider trading investigation; a corporate executive in a FINRA probe for alleged trading during a blackout period; a financial institution executive in an SEC investigation into statements in annual and quarterly filings; and a private fund founder in a DOJ investigation into alleged misappropriation of fund assets. Scott defends clients against DOJ, the SEC, the CFTC, FINRA, and state securities regulators—and he knows how the government uses trading data, chat logs, and electronic communications to build these cases.
Does Scott Armstrong Defend Clients in False Claims Act and Qui Tam Cases?
Yes. Scott defends healthcare providers, government contractors, and executives against False Claims Act (31 U.S.C. §§ 3729–3733) investigations, qui tam whistleblower lawsuits, and procurement fraud allegations. Representative matters include defending several cardiologists against an FCA complaint alleging false Medicare claims for radiopharmaceuticals in connection with nuclear stress testing, and an executive in a DOJ investigation involving procurement fraud and statements in Small Business Administration loan applications.
Scott represents clients at every stage of an FCA case: responding to Civil Investigative Demands (CIDs), during the sealed phase of qui tam actions, through DOJ intervention decisions, in settlement negotiations, and at trial. His healthcare FCA defense is built on his experience as lead counsel in DOJ healthcare fraud cases involving over $600 million in false and fraudulent claims.
Because FCA investigations often carry parallel criminal exposure and administrative consequences like OIG exclusion or debarment, Scott defends clients across civil, criminal, and administrative proceedings simultaneously.
Does Scott Armstrong Handle FCPA, Procurement Fraud, and Other Federal Criminal Investigations?
Yes. Beyond fraud and manipulation cases, Scott defends individuals in the full range of federal criminal investigations and prosecutions. Representative matters include: a former executive in an FCPA investigation involving exports of rare minerals from Africa; a former executive in a DOJ investigation involving mortgage fraud and false statements to federal lenders; an executive in a DOJ investigation involving procurement fraud and Small Business Administration loan applications; a former special forces operator in a DOJ investigation involving theft of government property; and an individual charged with conspiracy to commit bank and wire fraud and aggravated identity theft.
Federal investigations move fast and often begin long before a target letter or grand jury subpoena arrives. Scott’s nearly decade inside DOJ’s Criminal Division means he knows how prosecutors evaluate evidence, select charges, and decide whether to indict—knowledge he uses to resolve investigations quietly and pre-indictment whenever possible, and to try the case when it cannot be.
How Many Federal Jury Trials Has Scott Armstrong Tried?
Scott has tried sixteen complex cases in federal courts across the country. These were not simple, single-count matters. They included multi-week, multi-defendant federal jury trials involving Ponzi schemes, market manipulation, commodities fraud, healthcare fraud, anti-kickback statute violations, cryptocurrency manipulation, and prescription drug diversion—including the first-ever cryptocurrency securities manipulation trial under Title 15 and DOJ’s first data-analytics-driven opioid prosecution.
High-level trial experience with complex cases matters. Federal white-collar cases are resolved at every stage: pre-charge, post-indictment, and at trial. A defense attorney with proven first-chair trial experience changes the calculus for prosecutors at each of those stages. Scott’s sixteen federal trials give him the courtroom credibility to negotiate from a position of strength and to try a case if it cannot be resolved on favorable terms.
Does Scott Armstrong Handle Cryptocurrency Litigation, Asset Freezes, and Digital Asset Recovery?
Yes. Scott handles cryptocurrency litigation and digital asset recovery on both the offensive and defensive side, with a record of concrete results. He secured a federal Temporary Restraining Order freezing assets in multiple crypto wallets for a client whose approximately $12 million in cryptocurrency was stolen in a poison address hack, recovered over $2 million in USDT for a leading DeFi protocol following a smart-contract exploit, and represented an international payment-processing company in the recovery of over $5 million in stolen funds converted to cryptocurrency and laundered through online platforms.
On the defense side, Scott secured the complete dismissal of an Emergency Cease and Desist Order filed by the Texas State Securities Board against executives of the Apertum Foundation relating to the APTM token, secured the complete dismissal of an emergency federal TRO that improperly froze a crypto-trading executive’s accounts, negotiated the full withdrawal of a federal receiver’s approximately $1 million clawback demand, and has defended individuals against over $4 million in receiver clawback demands arising from crypto, securities, and commodities Ponzi schemes. He also represents an international crypto exchange against a law-enforcement freeze of approximately $2.5 million in stablecoins and a leading prediction market against user claims of fraud and breach of contract.
Scott’s command of blockchain technology, on-chain tracing, and the regulatory landscape across DOJ, the SEC, the CFTC, and FinCEN allows him to handle crypto disputes from emergency freeze proceedings through trial.
Does Scott Armstrong Handle Complex Civil Litigation and Business Disputes?
Yes. Scott represents businesses, executives, and individuals in high-stakes business disputes and complex civil litigation in federal courts nationwide. Representative matters include: a leading franchising company in a suit against a former executive for breach of contract, breach of fiduciary duty, fraudulent inducement, and unjust enrichment; the CEO of a leading skin substitute product against breach of contract and non-disclosure agreement claims; a money-transmitting business in a multi-million dollar dispute with a leading cryptocurrency service provider; an AI executive in a dispute with a DeFi protocol over cryptocurrency locked in the protocol’s smart contract; and a private equity principal in an employment dispute involving breach of employment and limited partnership agreements, discrimination, and retaliation claims.
Scott litigates business disputes in the same heavily regulated industries where he defends criminal matters: healthcare, financial services, government contracting, and digital assets. His DOJ experience building and trying complex fraud cases translates directly—he knows how to develop case theories, manage discovery in document-intensive matters, and present evidence to a jury.
Scott approaches every civil dispute with trial preparation as the baseline. That posture strengthens every phase, from early resolution through dispositive motion or verdict.
Does Scott Armstrong Represent Clients Nationwide?
Yes. Scott Armstrong is based in Washington, D.C. and defends individuals and companies in federal courts across the country. He has appeared in matters involving federal prosecutors, regulators, and state attorneys general nationwide, including DOJ, the SEC, the CFTC, FINRA, DEA, FDA-OCI, the Texas State Securities Board, and the New York and Maryland Attorneys General.
Federal white-collar investigations originate from DOJ’s Fraud Section in Washington, D.C. and from U.S. Attorney’s Offices in every federal district. Scott tried cases and handled investigations in federal courts throughout the country during his nearly decade-long DOJ career, and he continues to defend clients wherever a federal or state agency brings an investigation or case.
Scott’s co-founding partner, Drew Bradylyons, is the former Chief of the Financial Crimes and Public Corruption Unit at the U.S. Attorney’s Office for the Eastern District of Virginia. Together, they bring over 25 years of combined DOJ experience and 25 federal jury trials to every defense engagement, regardless of jurisdiction.
