Mary Mulligan is co-head of Friedman Kaplan’s white collar criminal defense practice. Over the course of her more than 30-year career, she has handled matters involving virtually all aspects of white collar crime and internal investigations. She has been described by the New York Law Journal as a “heavy hitter” in the white collar defense bar and is renowned for her work handling high-profile cases for clients and significant, confidential matters resolved behind the scenes which are not publicized.
Today, she represents clients in the financial services and other industries in connection with allegations of money laundering, insider trading, Foreign Corrupt Practices Act violations, criminal antitrust violations, securities fraud, tax fraud, off-label marketing, False Claim Act violations, mail and wire fraud, Federal Election Campaign Act violations, public corruption, healthcare fraud, and other matters. She has also served as an integrity counsel to a hedge fund and as a monitor in the construction industry, and handles a variety of matters involving institutions of higher education, including advising on governance, intellectual property, Title IX issues, allegations of sexual assault and abuse, conducting internal investigations, and responding to local, state, and federal inquiries.
Mary previously served as an Assistant United States Attorney for the Southern District of New York, directing investigations and prosecutions of fraud, public corruption, and financial crimes.
Because of the nature of Mary’s work, many of her most successful matters have not resulted in public charges and remain confidential.
