Member / Co-chair, White Collar Defense and Government Investigations Practice

[email protected]



Peter is a preeminent white collar defense attorney who specializes in assisting individuals facing charges or investigations, particularly involving financial and health care laws and political corruption probes. His current clients include a banker accused of violating the Iranian sanctions, individuals responding to investigations of alleged collusion in the 2016 presidential election, and major figures in the canceled Bahamas Fyre Festival. His experience as special assistant to the Justice Department’s Civil Division head and a three-year tenure as a federal prosecutor in New York informs his practice.

Peter is Co-chair of Mintz’s national White Collar Defense & Government Investigations Practice. He has represented high level officials at investment banks in many of the major financial investigations of the past decade, including the numerous inquiries into mortgage backed securities in the financial crisis, the rate fixing investigations, the use of confidential information at financial institutions, and the Madoff investigation, where he has represented Ruth Madoff for years.

This past year, for example, Peter has represented three individuals in the Congressional and Special Counsel investigations into alleged collusion in the 2016 Presidential election, along with two prominent investors in the Fyre Festival investigation. He has also recently assisted in a major sanctions matter. In addition, Peter has been representing the third bond broker accused of lying in the sale of RMBS and a physician accused of participating in a $50 million healthcare fraud scheme in New York.

Along with his extensive experience working with various arms of the Department of Justice, US Attorney’s Offices across the nation, state and federal regulators and FINRA, he has been involved in some of the most sensitive and consequential inquiries conducted by Congress and the SEC in these areas. He comes to these cases with service in Washington as a special assistant to the head of DOJ’s Civil Division, three years as a federal prosecutor in New York, and nearly 25 years as a senior partner at one of the nation’s foremost white collar boutiques.

In addition to his work in the financial arena, Peter has a long history of representing individuals and institutions accused of health care fraud and abuse, ranging from hospitals to medical service providers. And in his 35 plus year career in white collar/government investigations, he has represented individuals investigated for political corruption, antiquities fraud, and construction fraud. He has represented a sitting mayor, the chief judge of a state’s highest court, and a major league baseball team involved in the Clemens case. He also has represented numerous physicians and attorneys facing disciplinary proceedings.

In his career, Peter has tried nearly 20 matters to verdict and handled nearly the same number of appeals. He has been able to secure dismissals of cases post-indictment (including two charging securities fraud and one charging the largest conspiracy to illegally import antiquities in US history).

Peter has been named to Chambers for many years, being included in Band One for White Collar for many years, and has been named to Best Lawyers and Super Lawyers for over a decade as well. He has also been recognized by Who’s Who, Expert Guides, and has won the International Law Office and Lexology Client Service Award twice. Chambers quoted clients who said that he is “a brilliant tactician, super-efficient, an amazing negotiator, extremely creating and client-focused….He will do everything he possibly can to get the best result.” One client testified that he is ‘the most professional lawyer…along with being the hardest-working, and an exceptionally brilliant person.’”
