TRES ELLIS

Assistant Principal, Hill Country MS


I’m looking forward to another year as Assistant Principal at Hill Country Middle School, partnering with our exceptional staff to continue to cultivate a positive campus culture that reflects the Cougar values and vision of our leadership. This is my 35th year in education and 9th in administration. Prior to joining the staff here at HCMS I served as an Assistant Principal in Lake Travis ISD where I had the honor to open the new Bee Cave Middle School campus following one year at Lake Travis Middle School. Previously, I spent 10 years at Westlake High School as a Head Basketball Coach and AP Psychology/Teen Teaching (Leadership) teacher. My other experience in the Austin area, besides growing up here, includes being Head Basketball/Cross Country Coach and Psychology/Sociology teacher at Austin High. I began my career with seven years at New Braunfels Middle School as a teacher and coach, so it has been especially rewarding to return to working with students at such a formative age—when building strong character and sound decision-making skills is so important. Due to my continued love for coaching, I also serve as the Head Boys Basketball Coach at The Austin Waldorf School.  My wife Laurie is also a teacher in Eanes ISD and has been a 4th-grade teacher at Forest Trail Elementary since 2002. We have two daughters, Megan (WHS ‘16 & Texas A&M ‘20) and Emily (WHS ‘20 & Texas A&M ‘24) who I am proud to say are both thriving in their careers. When I'm not at school I enjoy running the trail at Town Lake, walking my dogs and live music.

BRETT LA BISSONIERE

Assistant Principal, Hill Country MS


I am looking forward to another year of being an Assistant Principal at Hill Country Middle School. My teaching career began at West Ridge Middle School where I taught 7th grade science for 9 years. I am originally from the suburbs outside of Philadelphia and went to Penn State University, where I majored in Secondary Education with Biology and minored in Psychology. Throughout my teaching career at WRMS, I served as the science department head, the National Junior Honors Society co-sponsor, and a member of many committees. District-wide, I have served on the District Leadership Team, I was a member of the fifth cohort of the Institute for Excellence, and I was named the Eanes ISD District Educator of the Year for the 2020-2021 school year. In 2023, I earned my Master's Degree in Educational Leadership and Policy Studies from the University of Texas at Arlington and joined the HCMS leadership team that summer. Outside of school, I enjoy traveling and doing all outside activities with my husband and 20 month old son.

BRAD CORBETT

Assistant Principal, Hill Country MS


My name is Brad Corbett, and I am excited to begin my second year as an Assistant Principal at Hill Country Middle School. Before moving into administration, I spent 20 years in the classroom, including 15 years serving students in Eanes ISD. Throughout my career, I have had the privilege of teaching in both general education and special education settings, working with students from kindergarten through 8th grade. HCMS holds a special place in my heart, as I taught here a decade ago and am grateful for the opportunity to once again be part of this incredible community. At the heart of all my work is the simple belief that relationships matter most. I believe that relationships are the foundation of everything we do here. Through strong relationships students thrive, families feel connected, and staff feel valued.
