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! 

  • Hello, I'm Andy Hartshorn! I'm excited to begin my second year as Assistant Principal at Brentwood Middle School. I have been in education for 23 years, spending about 5 years teaching mathematics at Frederick High School followed by 14 years teaching mathematics at Greeley Central High School. I have spent the rest of my career at Brentwood Middle School as an instructional coach, IB coordinator, teacher, and AP. 

    Outside of school I spend my time with my wife Jessica and our two sons, Aiden and Gavin. In addition to our human family, we have two dogs: Tic and Mac, and three cats: Bertha, Queso, and Charlie. 

    My goal in education is to support students and families to maximize learning academically and socially to prepare students for the next step in their life - initially high school, then either college or career. I believe education is the great equalizer and my hope is to help students at Brentwood as they navigate the world of middle school and grow into the amazing humans that they are.

    Every day is a great day to be a Bengal!
