Christopher Conniff is an experienced trial lawyer who represents clients in investigations and cases involving the full spectrum of white collar criminal and regulatory matters. Since leaving public service in 2007, Chris has helped both individuals and organizations across the financial services, private equity, health care, and life sciences industries navigate through a number of high-profile government investigations, including in the areas of securities fraud, insider trading, public corruption, health care fraud, and criminal antitrust. He regularly appears on behalf of his clients before the U.S. Department of Justice, U.S. Securities and Exchange Commission, Commodity Futures Trading Commission, and FINRA, as well as various state attorneys general.

While at the USAO, Chris led the team that prevailed in the highly publicized prosecution of more than 30 members and associates of the Gambino Organized Crime Family of La Cosa Nostra, including the Family’s Acting Boss and Underboss. He also served as lead trial counsel in the successful prosecution of the members of an international arms trafficking organization. Chris’s other significant cases include the prosecution of two founders of a publicly-traded payment services company charged with money laundering in connection with their transfer of billions of dollars from United States customers to overseas internet gambling companies.
