GFPS trustees vote to add Nathan Reiff to board MTN and last updated 2021-07-21 01:07:00-04 GREAT FALLS â The Great Falls Public Schools Board of Trustees voted unanimously on Monday evening to add Nathan Reiff to the board. Now that Reiff is a board member, he plans to hit the ground running and start learning as much as he can from the rest of the board while he serves the remainder of Jan Cahillâs term. Cahill âThose are big shoes to fill⦠but Iâd like to be in the schools and talk to the public and kind of understand what they want,â Reiff said. âSome of itâs going to be learning and listening to the board⦠but Iâm glad I have an experienced board with me, so I donât have to learn alone.â
