Marshall L. Miller rejoined the firm after serving as the Principal Associate Deputy Attorney General of the United States from June 2022 through December 2024. In that role, he was a member of the U.S. Department of Justice (DOJ) senior leadership team responsible for leading and supervising all DOJ personnel and components. For his service, Marshall received the Edmund J. Randolph Award, DOJ’s highest honor, bestowed on an individual who has made an outstanding contribution to the DOJ mission.

At Hecker Fink, Marshall’s practice focuses on working with individuals, corporate executives, boards of directors, companies, non-profits, and universities to solve their most complex legal problems. He helps clients navigate internal investigations, whistleblower complaints, compliance challenges, data breaches, regulatory issues, civil litigation, and government enforcement inquiries, actions, and prosecutions. Marshall has particular experience in financial, accounting, anti-corruption, anti-money laundering, civil rights, international enforcement, national security, and data security and privacy matters, as well as extensive experience trying cases to verdict.

Previously, Marshall served as the highest-ranking career official in the Criminal Division, overseeing the Department’s most significant criminal matters, highest-profile prosecutions, and most important programs, such as its Fraud Section, its Foreign Corrupt Practices Act (FCPA) program, its Health Care Fraud Strike Force, its Office of International Affairs, its Money Laundering & Asset Recovery Section, and its flagship cybercrime and public corruption units. Marshall worked to develop and implement the Department’s strategic priorities and policies, including steering its policy on corporate cooperation with DOJ investigations. He testified on Capitol Hill and provided briefings and counsel to Congressional staff and executive branch officials, with an emphasis on cybersecurity, asset forfeiture, and anti-corruption measures. Following Marshall’s departure from the DOJ, Attorney General Loretta E. Lynch lauded Marshall as “an outstanding attorney, a remarkable public servant, and an unwavering advocate for the principles of justice.”

Marshall has received substantial recognition for his work. At DOJ, Marshall received the Department’s highest award, the Edmund J. Randolph Award, as well as the Attorney General’s Award for Excellence in Furthering the Interests of National Security, the Director’s Award for Superior Performance, and the Federal Law Enforcement Foundation’s Prosecutor of the Year Award. He was awarded the Henry L. Stimson Medal by the New York City Bar Association, recognizing the EDNY’s most outstanding AUSA in the Criminal Division, and the J. Michael Bradford Award, presented by the National Association of Former U.S. Attorneys for the most outstanding performance by an AUSA nationwide. He is also the winner of a National Intelligence Merit Award, presented by the Director of National Intelligence. Global Investigations Review honored him with its annual award for the “Best Speech on White Collar Enforcement.”

Marshall previously taught at New York University (NYU) Law School as an Assistant Professor and an Adjunct Clinical Professor, co-founded the EDNY’s Federal Criminal Prosecution Clinic, and taught National Security Law at Fordham University. He also served as the Chair of the White Collar Crime Committee of the New York City Bar Association.
