Mike Gass chairs the firm’s Securities Litigation & Corporate Governance Group. Over his 25 year career he 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. 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.
