I have lived in Austin since 2017 and began serving Hill Country Middle School in 2018 as a school counselor. Prior to being a part of the Eanes community I was the middle school counselor for Jarrell Middle School. I have also been an elementary school counselor in Killeen ISD and taught at the elementary level in grades 1, 2 and 4 in Killeen ISD and Salado ISD. I am excited to serve the inspiring staff and students of Hill Country as an assistant principal. I enjoy working with middle school level students and being a part of this incredible time of growth in their lives.

KIMBERLY DEWRELL
I recently relocated to the Austin area and am excited to take on the role of AP at Hill Country Middle School. I bring 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, and Principal at J.F. Tatem Elementary School in Haddonfield, New Jersey.
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.
