Portrait of Steve Zimmerman
Steve Zimmerman - Principal
While originally born in Kentucky, I moved to San Antonio soon after. As the son of a career military man, I was fortunate enough to see a great deal of the country, living in Kentucky, Virginia, Colorado, and Texas. I have been fortunate to travel extensively and experience the many diverse cultures and climates that our great country has to offer. A product of the public education system, I was fortunate enough to attend all four years of high school in Northside ISD where I participated in basketball. Because of my personal experiences, I believe that involvement in extracurricular and co-curricular activities is a vital part of the overall experience each student should enjoy before leaving high school. After completion of my high school studies, I went on to receive a Bachelor of Arts degree from St. Mary's University. I remained in San Antonio and in 1995 began my teaching and coaching career at New Braunfels Canyon High School. In 1998 I had the opportunity to work at Judson High School and in 2001 was hired at Winston Churchill High School. In 2008 I earned a Master of Education in Teaching from Schreiner University and became an assistant principal at Johnson High School. In the spring of 2013, I was appointed as the principal of Driscoll Middle School; four years later, in 2017, I was given the opportunity to become the principal at Madison. And in July of 2020, I was given the honor of being named the principal of Tom C. Clark High School. I look forward to working with you and your student(s) as I begin my service to the Clark community.

On a more personal note, while you will see me at all things Clark during the school year, I do have a few interests outside of education. When not working at school or attending a school event, I enjoy golfing, hunting, and saltwater fishing.

I am originally from Oklahoma where I graduated from Oklahoma State University with my Bachelor's in Education. I began my teaching career in Texas at Richardson ISD as a middle school math teacher. I spent 5 years as a Math Specialist in NEISD. After that I began my career as an administrator at Driscoll Middle School, and then at Madison High School. I am happy to be a Clark Cougar now! Outside of being in education, I have one daughter who means the world to me. I like to stay active by running, swimming, strength training, and hiking outdoors.
