Mr. Nasson is a partner in the firm’s Boston and New York offices. His practice focuses on regulatory enforcement, white collar criminal defense, internal investigations, and complex civil litigation.

Mr. Nasson represents corporations and individuals in criminal and civil matters brought by the Department of Justice, Securities and Exchange Commission, and other federal and state enforcement agencies. He also counsels clients on risk mitigation strategies with respect to anti-corruption, sanctions, cybersecurity, and anti-money laundering issues.

During his six years as a federal prosecutor, Mr. Nasson led investigations involving insider trading, market manipulation, health care fraud, 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, medical professionals, and attorneys in a number of high profile cases, including a $300 million market manipulation prosecution.
