Mr. Andy Hartshorn

After about 20 years teaching high school mathematics (the last decade and a half at Greeley Central), I am excited to become part of the Brentwood staff as the IB Coordinator and Instructional Coach. Visit me in the main office for anything IB or just to come say hi! I look forward to spending the remainder of my career with the amazing students and staff at Brentwood and I can't wait to see what we can accomplish together!
