Benjamin G. Greenberg is the former U.S. Attorney for the Southern District of Florida. Ben counsels corporations and individuals on white collar matters and an array of regulatory issues, as well as advising them in connection with investigations and compliance. He utilizes his experience to help clients navigate local and national issues involving the Department of Justice. Ben is an experienced trial attorney who has tried more than twenty cases to verdict. He has in-depth experience handling a wide range of government investigations, including the Foreign Corrupt Practices Act (FCPA), health care fraud, financial institution fraud, money laundering, the Bank Secrecy Act, and the False Claims Act (FCA). His deep experience in health care fraud matters derives from his role as U.S. Attorney in Florida, which consistently ranks as the number one state in the nation for the volume of health care fraud matters, the dollars lost in them, and dollars collected in their prosecution.

As the U.S. Attorney for the Southern District of Florida, Ben served as the chief federal law enforcement officer for one of the largest and busiest offices in the country, responsible for overseeing more than 200 attorneys and close to 500 employees. In this capacity, Ben worked closely with the Criminal Division and the National Security Division in Washington to supervise high profile and complex cases in South Florida. Ben also traveled abroad to meet with senior law enforcement officials regarding joint investigations and to develop strategies for combatting transnational crime.

Previously, Ben held a variety of senior management positions at the U.S. Attorney’s Office, including First Assistant U.S. Attorney, where he actively participated in and approved major investigative and prosecutorial decisions in all areas of criminal litigation, including FCPA, white collar, money laundering, and national security cases, as well as in civil cases under the FCA and the Federal Tort Claims Act. His other roles within the U.S. Attorney’s Office for the Sothern District of Florida include chief of the Narcotics Section, chief of the Special Prosecutions Section, and Deputy Chief of the Major Crimes Section.
