Ben is a member of the firm’s nationally ranked Government Investigations and White Collar Litigation department. A former federal prosecutor, he is equally skilled in the courtroom as he is in handling clients’ most sensitive, high-profile internal matters. He regularly advises corporate entities, boards of directors, audit and special committees, and individuals on their most difficult legal challenges. Ben has particular expertise in criminal and civil fraud matters, with a focus on cross-border Foreign Corrupt Practices Act (FCPA) and Office of Foreign Assets Control (OFAC) sanctions investigations and litigation, as well as significant experience with congressional investigations and crisis situations.

Over the past several years, Ben has been at the forefront of several groundbreaking, global resolutions for corporate entities facing criminal and civil exposure arising from the same conduct in multiple jurisdictions. His experience in navigating the process of cooperation and resolution with regulators spread throughout the world simultaneously has made him uniquely qualified to manage these special situations. He is among only a handful of U.S. lawyers who have achieved these types of global results and is at the forefront of this emerging trend of international criminal law.

Ben’s practice also has included helping clients in politically-charged investigations conducted by the U.S. Department of Justice, U.S. Securities and Exchange Commission (SEC), U.S. Federal Elections Commission, and other federal agencies. He often plays a role in advising clients through strategic communications and crisis management.

Prior to joining McGuireWoods, Ben was a federal prosecutor with the Fraud Section of the U.S. Department of Justice’s Criminal Division. In that role, he prosecuted foreign bribery, financial, and healthcare fraud throughout the United States. Ben was the lead on several jury trials, and managed large-scale corporate investigations.
