A former prosecutor in the U.S. Attorney’s Office for the Southern District of New York, David Massey is Co-Chair of the firm’s White Collar & Investigations practice. He leads global companies, board committees, and senior executives through high-profile civil litigation, cross-border investigations, and criminal prosecutions.
David has obtained favorable results for clients, including dismissal of claims, nonprosecution agreements, deferred-prosecution agreements, and declinations, in a broad range of complex matters. He has represented dozens of defendants, witnesses, subjects, targets, and victims in civil litigation, internal investigations, and government investigations. These include matters relating to accounting practices, corporate governance and disclosure, insider trading, securities fraud, foreign and domestic corruption, economic sanctions, money laundering, bank fraud, bankruptcy fraud, wire fraud, and tax fraud.
As a federal prosecutor for nine years in the Southern District of New York, David focused on complex cross-border fraud cases as a member of the Securities and Commodities Task Force. He tried 12 cases, argued 10 appeals before the U.S. Court of Appeals for the Second Circuit, and secured the first-ever indictment and guilty plea of a non-U.S. bank for tax fraud.
David has been recognized by Chambers USA, The Legal 500, Global Investigations Review, Best Lawyers in America, and the National Law Journal for his work in white-collar defense. Chambers USA has praised David as an "incredibly careful, smart and good lawyer," “a great litigator and clear communicator,” and a “super talented lawyer” with “skill in seeing the overall strategy and seeing long-term where things are going.”
