Mr. Nasson is a partner in the firm’s Boston office. His practice is focused on government enforcement, white collar criminal defense, securities enforcement, internal investigations, corruption-related matters, and complex civil litigation.

Prior to joining the firm, Mr. Nasson served as an Assistant U.S. Attorney in the Business & Securities Fraud Section of the U.S. Attorney’s Office for the Eastern District of New York. Prior to that, he served as an Assistant U.S. Attorney in the White Collar Crime Section of the U.S. Attorney’s Office for the Eastern District of Kentucky.

During his six years as a federal prosecutor, Mr. Nasson supervised investigations involving insider trading, market manipulation, cybercrime, securities and bank fraud, embezzlement, tax evasion, and espionage, as well as violations of the Foreign Corrupt Practices Act, Export Administration Regulations, and International Traffic in Arms Regulations. As a white collar prosecutor, Mr. Nasson led a multi-district, multi-agency investigation of an international cybercrime ring, the first criminal prosecution in the U.S. involving trading on inside information obtained through hacking. Mr. Nasson has also investigated and prosecuted corporate executives, broker-dealers, stock promoters, and attorneys in a number of high profile cases, including a $300 million market manipulation prosecution. He tried more than a half-dozen cases to verdict — all resulting in convictions — in addition to arguing appeals before the U.S. Courts of Appeals for the Second and Sixth Circuits.
