Samson “Sam” Enzer is a distinguished former federal prosecutor and an accomplished trial lawyer, investigator, and problem-solver. Sam focuses on representing companies and individuals in high-stakes criminal and regulatory enforcement matters, internal corporate investigations, and civil litigation, often in cases involving the finance and cryptocurrency industries. Sam also regularly advises clients on regulatory compliance and transactional due diligence relating to cryptocurrency. For his achievements in the cryptocurrency space, Sam was named a 2022 Law360 MVP in FinTech and a 2022 National Law Journal Cryptocurrency/Blockchain/FinTech Trailblazer.

Sam has secured successful outcomes for preeminent corporations and individuals in some of their most challenging criminal and civil matters, including in inquiries by the Department of Justice (DOJ), Securities and Exchange Commission (SEC), New York Attorney General (NYAG), and other regulators. During his combined experiences as a federal prosecutor and defense lawyer, Sam has also won numerous jury and bench trials, appeals, and hearings.

Described as “one of the leading cryptocurrency enforcement practitioners to come out of government service in recent years” by The National Law Journal and as the “SDNY Crypto Ace” by Law360, Sam has been sought out by digital asset trading exchanges, blockchain startups, asset managers, banks, and businesspeople looking for guidance on regulatory risks concerning cryptocurrency. Prominent entrepreneurs have entrusted their gravest cryptocurrency enforcement challenges to Sam, including a FinTech startup founder accused by DOJ of laundering $4.5 billion in stolen bitcoin. Sam is also a member of the Wall Street Blockchain Alliance and is a frequent speaker, news commentator, and author on cutting-edge issues concerning the regulation of cryptocurrency, non-fungible tokens (NFTs), stablecoins, and other digital assets.

Before joining Cahill, Sam served for eight years in DOJ as an Assistant United States Attorney in the United States Attorney’s Office for the Southern District of New York (SDNY), where he rose to become a senior member of the SDNY Securities and Commodities Fraud Task Force. As a federal prosecutor at SDNY, Sam led numerous high-profile investigations and prosecutions of a broad range of white collar crimes, including multiple groundbreaking cryptocurrency enforcement matters. For example, Sam spearheaded the first securities fraud prosecution in SDNY history arising from an initial coin offering (ICO) of cryptocurrency tokens, and led the prosecution of McAfee antivirus software founder John D. McAfee on securities fraud, commodities fraud, wire fraud and money laundering charges arising from deceptive cryptocurrency promotions. Sam also won a hard-fought guilty verdict on all insider trading charges against a former investment banker in a closely watched, difficult retrial.

During his tenure at SDNY, Sam was nominated for the United States Attorney General’s Distinguished Service Award in 2018 and received the Federal Law Enforcement Foundation’s Prosecutor of the Year Award in 2014.

Before his time at SDNY, Sam worked as a litigation associate at another major law firm and clerked for United States District Judge Louis L. Stanton. Sam graduated cum laude from the University of Pennsylvania Law School, where he was a senior editor of the University of Pennsylvania Law Review.

An active member of his community, Sam serves on the lawyers’ advisory council for a non-profit organization offering educational opportunities to underprivileged inner city youth, and provides pro bono legal services to indigent criminal defendants.
