Mr. Marshall Hester

I’m super excited to start another year at MAC!

I've taught so many subjects for 15 years in Austin; including Biology, IPC, Forensic Science, Aquatic Science and even AVID.  But I’ve discovered my true passion in AP Environmental Science as I continue to teach my beloved Biology.

My family moved back to San Antonio so that the grandparents could spend more time with the grandkids, Lola and Atticus.

I’m a Longhorn superfan (at least when we’re winning) after graduating from The University of Texas at Austin with my Bachelor’s of Science in Biology with an Ecology and Evolution focus.  I’m also a proud alumnus of the UTeach Program, a nationally-distinguished education preparation and certification program.
