For 7 years, no two days have been the same. The enthusiasm and creativity of Mullen High School, especially our energetic students, keep me happy to pull into the parking lot. The Counseling Program has given me the chance to delve a little deeper into the challenges as well as the gifts of some of our students. Watching them grow in their confidence, resiliency, and self-advocacy is beyond gratifying.
