William B Mateja

Sheppard Mullin Richter & Hampton LLP


Bill has long been a white collar trial lawyer with a particular focus on healthcare fraud and securities enforcement. A former prosecutor at the highest levels of the Department of Justice, Bill was responsible for all the Department’s White Collar operations, as well as the day-to-day workings of its corporate fraud task force. He also served as Special Counsel for Health Care fraud overseeing all of the Department’s health care fraud enforcement. This experience makes him unusually adept at handling the collateral consequences of White Collar matters, which can occur in any of four separate legal forums — criminal, civil, administrative, and regulatory — sometimes all at once.
