Over the course of her more than 35-year career, she has handled matters involving virtually all aspects of white collar crime. 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.

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.

Today, she represents clients in connection with allegations of marketing manipulation, securities fraud, money laundering, insider trading, Foreign Corrupt Practices Act violations, criminal antitrust violations, tax fraud, off-label marketing, False Claim Act violations, mail and wire fraud, public corruption, computer fraud, healthcare fraud, art forgery and theft, and other matters. She has also served as an integrity counsel to a hedge fund and as a monitor in the construction industry.

Mary’s recent experience includes:

Serving as lead counsel in defense of the former Chief Financial Officer of Archegos Capital Management in a prosecution by the U.S. Attorney’s Office for the Southern District of New York, including through a 2024 nine-week criminal trial involving charges of RICO conspiracy, securities fraud, and mail and wire fraud relating to the family office’s 2021 collapse. In related civil actions, Mary and the firm previously obtained the dismissal of a CFTC enforcement action filed in the SDNY and continue to represent the client in a related SEC enforcement action and in a case brought by a former Archegos employee.

The representation was nominated by Global Investigations Review for its 2019 “Most Important Case of the Year” award.
