One of Crestline’s main fundraisers is the Boosterthon Fun Run! It’s a 9-day fun, healthy, and character-building program that kicks off with a Pep Rally and ends with fun run. The classrooms work together as teams to raise pledges that go to support a special project for Crestline. There are always fun surprises throughout the event and the kids love the energy and fun the Boosterthon team brings to Crestline. This year's Boosterthon will be held February 9-17th.
