Guy represents clients in internal and government investigations involving alleged violations of the Foreign Corrupt Practices Act (FCPA), earnings management investigations, allegations of scientific fraud and other types of alleged corporate misconduct. He represents companies and individuals before federal agencies, including the US Department of Justice (DOJ), the US Securities and Exchange Commission (SEC), and other federal and state agencies and attorneys general. Guy regularly works with clients to design, implement and test corporate compliance programs, and advises boards of directors on matters related to corporate compliance.

Guy has extensive experience with corporate monitorships. He has served both as a government-appointed monitor and as corporate counsel to companies placed under monitorship. Notably, Guy was appointed by the DOJ, SEC and Brazil’s Federal Prosecution Service (MPF) to serve as the corporate monitor related to Operation Car Wash, the largest corruption investigation in history.

Guy draws on years of experience as a federal prosecutor to help clients navigate their most sophisticated white-collar fraud matters. As a trial lawyer in the fraud section of the DOJ’s Criminal Division, he investigated and prosecuted all types of white-collar crime and public corruption throughout the United States, from grand jury through trials. During his tenure at the DOJ, Guy received many commendations from federal and state law enforcement agencies. Prior to joining the fraud section, Guy handled public corruption, organized crime, sex crimes and other matters as a federal and state prosecutor in South Florida.

Because of Guy’s varied experience, he is sought-after to assist with matters beyond the world of traditional corporate white-collar law. For example, he has handled investigations related to allegations of sexual misconduct, national security and art fraud.

The national media often calls on Guy for commentary because of his successful track record handling high-profile public corruption and white-collar crime matters. Outside of his practice, Guy teaches a course on corporate governance, ethics and compliance as an adjunct law professor at the University of Pennsylvania Carey Law School.
