Mrs. Harriet Wrabetz


I have attended high school in Nürnberg, Germany, and Friedrich-Alexander University in Erlangen, Germany, studying Chemistry. Education became my second passion, after science, when I went back to college to pursue my Bachelor’s in Science and Master’s in Educational Administration from Tarleton State University, Central Texas. I have also earned the post graduate degree of Educational Specialist at Liberty University.


I have enjoyed teaching and working with students both in Copperas Cove and Killeen ISD. Whether it was in second, third or fifth grade, to see students grow and develop a love for learning was the most rewarding experience. For the past eight years, I served in Killeen ISD as an Assistant Principal on Fort Hood and now here at Trimmier.

Math Center

I have had the honor to work as the administrator for the Killeen ISD Math Center after school and on Saturdays. We enroll on average over 600 students per school year, and I am proud to say that we always have some of our own Trimmier Tigers coming to the Math Center! 


My two daughters are my pride and joy and their education has always been a priority for me. My oldest daughter is in her second year of medical school at Paul L. Foster School of Medicine in El Paso and my youngest daughter is a senior at UT Austin. My family also includes two furry friends who wait for me at the end of the day with wagging tails. I have been told they are quite spoiled.
