Mulcahy represents and advises companies across a variety of industries in investigations and through all phases of litigation. Prior to joining the firm, Peter was Assistant Attorney General at the Environmental Protection Division of the Massachusetts Attorney General’s Office, where he investigated, litigated, and negotiated the settlement of civil violations of environmental laws, regulations, and related offenses on behalf of the Commonwealth.
