Hola! My name is Mark DeLeon, and I am so excited to serve as an Assistant Principal at Miller Middle School. This year will be my 22nd year in education. I taught Criminal Justice in San Antonio for 4 years before moving into school administration. Before education, I served as a police officer in the Houston area for 18 years. I received my Bachelor of Science degree in Criminal Justice from Wayland Baptist University and my Master's in Education Administration from Texas State University.

My wife, Cassie DeLeon, and I have been married for 26 years. We have lived in San Marcos for 25 years and are very proud to call this community our home. We have 6 incredible children and 4 awesome grandchildren. All my children have graduated from a 4-year university, with the youngest set to graduate in 1 more year.  

My mission is to create a safe and engaging environment in our schools that promotes optimal learning experiences for our students.  I believe that education is a gift and extends beyond just the classroom.  Given the appropriate environment and opportunities, ALL children can learn.

I truly value the benefits of education as my parents were migrant farm-workers and did not have the opportunity to attend school. I attended school with English as my second language and Spanish as my primary language. I was the first in my family to graduate from high school and attend college. 

It is my goal to connect with our students who come from all backgrounds and instill the value of education by sharing my journey and how education has been a great equalizer for me.
