The state president works in collaboration with the state director to advance AARP’s mission and priorities in the state. Livingston has experience in the Washington, D.C., broadcasting industry and has done consulting for television and radio stations nationwide. He also was chief operating officer of a $35 million advertising and public relations agency representing local, regional and national clients.
