Michael T. Gass

Practice Group Leader - Securities Litigation & Corporate Governance

Mike Gass chairs the firm’s Securities Litigation & Corporate Governance Group. Over his 30 year career Mike has developed a remarkably broad and deep experience base in representing companies and their management and boards in high-stakes matters involving the securities laws and shareholder claims. Mike’s practice has increasingly focused on FCPA compliance and enforcement matters as the SEC and DOJ have prioritized FCRA enforcement in recent years. He has represented a wide range of clients in both private litigation – primarily shareholder class actions and derivative actions – and in investigations and enforcement actions brought by government and industry enforcement agencies. His expertise has made him a “go-to” counselor for management seeking governance advice, and for boards and their committees in exercising their oversight responsibilities, particularly with respect to the delicate and challenging task of investigating and remediating alleged misconduct within the organization.

Mr. Gass is listed in Best Lawyers in America and Massachusetts Super Lawyers.
