KIMBERLY DEWRELL

Principal, Hill Country MS


I bring over 18 years of experience within the education field, working with students ranging in age from Kindergarten through 8th grade in various roles and learning environments. I have been a 5th and 6th-grade teacher, a K-8 Instructional Coach/Staff Developer, Middle School Vice Principal at the Upper Middle School in Montgomery Township School District, Principal at J.F. Tatem Elementary School in Haddonfield, New Jersey and Assistant Principal at Hill Country Middle School.

While I enjoy working with all grade levels, I am excited to return to middle school. This age group is delightful, as each student explores who they are as a person. You have days full of curiosity, angst, and laughter; I wouldn’t have it any other way. I hope to impact all facets of learning for our students in a positive manner.

Assistant Principal, Hill Country MS


I am excited to return to Eanes ISD to serve as an Assistant Principal for Hill Country Middle School and work with the incredible staff to continue to make HCMS a special place for our students and community. This is my 32nd year in education and 5th 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 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 spent the first 7 years of my career at New Braunfels Middle School as a teacher and coach so I have enjoyed returning to work with students at the age when it is so important to develop good character and decision-making skills.  My wife Laurie is also a teacher spending the past 22 years as a 4th-grade teacher at Forest Trail Elementary in Eanes ISD. We have two daughters, Megan, Texas A&M class of 2020, and Emily, a senior at Texas A&M. When I'm not at school I enjoy outdoor activities and live music.
