About William C. Pericak
William Pericak is a former federal prosecutor who has spent more than 25 years as a first-chair trial lawyer. He brings that experience to bear in his representation of individuals and companies in government investigations. As a former leader of a health care fraud unit within the Department of Justice (DOJ), a deputy criminal chief in a US Attorney's Office, and the supervisor of criminal prosecutions arising from the Deepwater Horizon oil spill, he offers unique insight and credibility to clients facing government scrutiny.
Experience at the top
During Bill's distinguished career as a prosecutor, he supervised Health Care Fraud Strike Force attorneys across the country as an assistant chief in DOJ's Criminal Division, Fraud Section. Before that, he served as an assistant US attorney and deputy criminal chief in the Northern District of New York, where he conducted and oversaw investigations of a range of offenses, including bribery, kickbacks, fraud, money laundering, smuggling and sanctions violations. Following the Deepwater Horizon explosion and oil spill in the Gulf of Mexico, he was appointed director of the DOJ Deepwater Horizon Task Force, overseeing criminal prosecutions related to the fatal environmental disaster.
Bill helps clients confront claims of wrongdoing asserted by the government, third parties or internal sources. He regularly represents health care entities (including physician group practices, hospital systems, coding companies and billing companies), government contractors and commercial enterprises. The matters he has worked on for these clients have touched on claims of bribery, kickbacks, discrimination, environmental crimes, and FCPA and sanctions offenses, and violations of the federal Anti-Kickback Statute and the False Claims Act.
Over the course of his career, Bill has tried 20 cases to verdict and argued 25 appeals. His decades of experience allow him to rapidly assess the strengths and weaknesses of cases, and to identify the most advantageous next steps. His reputation in the criminal defense bar and among government prosecutors ensures that he is heard and increases the likelihood of favorable resolutions.
Much of Bill's practice is devoted to defending parties against civil lawsuits and criminal prosecutions. He also helps clients conduct internal investigations after being alerted to possible violations, and design compliance programs that minimize the chance of future civil or criminal liability.
