Mary Mulligan has broad and deep experience in white collar criminal defense and internal investigations: over the course of her more than 25-year career, she has handled matters involving virtually all aspects of white collar crime. 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, Internet fraud, healthcare fraud, cyberstalking, 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 and secondary schools, including advising on governance, intellectual property, and Title IX issues, conducting internal investigations, and responding to local, state, and federal inquiries.

From 1997 to 2002, Ms. Mulligan served as an Assistant United States Attorney for the Southern District of New York, directing investigations and prosecutions of fraud, public corruption, and financial crime. During this time, she led the government's largest FCPA investigation to date, which involved the alleged payment of tens of millions of dollars in bribes to the president of Kazakhstan in connection with major oil transactions in the 1990s.

Because of the nature of Ms. Mulligan’s work, many of her most successful matters have not resulted in public charges and remain confidential.
