“Riverdale 101,” September 3rd, 9 to 10:30 am, Gym Lobby. Join RHS vets and newbies to mingle, chat and enjoy some refreshments as we kick off the new school year. Meet the PTC board members and learn a little more about how the high school operates. Principal Paula Robinson and counselor Michael Murray will make brief appearances, and there will be plenty of parents who can answer questions and provide insight. Hope to see you there.
