Benjamin D. Singer represents multinational corporations and their boards and executives in high-stakes criminal and civil investigations by the U.S. Department of Justice, Securities and Exchange Commission, and other federal and state agencies. Ben joined O’Melveny after a decade at DOJ, where he most recently served as Chief of the Department of Justice’s Securities & Financial Fraud Unit.
In this role, Ben was the lead prosecutor on several of the largest cross-border cases in DOJ history, including Volkswagen’s alleged evasion of U.S. emissions standards, the foreign exchange manipulation cases, and cases alleging LIBOR manipulation.
Prior to that, Ben was the Chief of the DOJ’s Health Care Fraud Unit, where he supervised corporate health care prosecutions involving major health care providers, pharmaceutical manufacturers, and medical device manufacturers.
As Chief of the DOJ’s Securities & Financial Fraud Unit, Ben oversaw approximately 50 federal prosecutors investigating complex securities, commodities, and other corporate fraud and corruption offenses, including market manipulation, spoofing, insider trading, accounting fraud, procurement fraud, money laundering, environmental crimes, antitrust offenses, and bribery.
As Chief of the DOJ’s Health Care Fraud Unit, Ben supervised a team of over thirty prosecutors that prosecuted offenses in the health care industry, including fraud, kickbacks, money-laundering, and FCPA-related offenses.
Ben is a formidable trial lawyer, having served as first-chair trial counsel in eight felony white-collar jury trials during his time at the DOJ. His work twice earned him the DOJ’s highest honor: the Attorney General’s Award.
Prior to his government service, Ben worked in the New York office of two international law firms.
