Mr. Andy Hartshorn

After about 20 years teaching high school mathematics (14 years at Greeley Central), I have had the privilege of joining Brentwood Middle School initially as a Instructional Coach/IB Coordinator and now as one of the Assistant Principals! Brentwood is an amazing place for amazing students and staff and I enjoy working with them all!
