Investigations & White Collar Defense

Our Investigations and White Collar Defense team has considerable experience representing businesses and individuals in government investigations and enforcement actions as well as conducting internal investigations. Clients rely on us to be their trusted partners before or after the government initiates an enforcement action. Our talented team regularly advises and represents clients in healthcare fraud, government contract fraud, tax fraud, violations of the Anti-Kickback Statute, mail and wire fraud, money laundering, false statements, worksite enforcement actions, and government program fraud.

Clients also look to us to conduct internal investigations into complex and sensitive matters. With dozens of internal investigation under their belts, our team is adept at evaluating risk and implementing prevention and compliance measures. Importantly, we are able to draw on the knowledge and abilities of our experienced regulatory and industry professionals to develop comprehensive strategies that address not only the case at hand, but the public, media, and related consequences of enforcement actions.
