I have been working at Johnson since the school opened serving as an English IV teacher and the Head Boys Basketball Coach.  I graduated in 1986 from Clark High School, then earned a BS in Kinesiology from Texas A&M University.  

In 1991, I started coaching in South San ISD.  After five years, I moved to Clark HS, where I worked for two years.  I accepted my first head coaching position at Smithson Valley HS, staying there four years.  Next, I moved to Warren HS, where I was the head coach for six years. Finally, I moved to Johnson, where I will be starting my 13th year.

I have a son, Zachary, who graduated from Johnson in 2019 and is now playing basketball at St. Mary's here in San Antonio.  He is 20 years old.

I feel extremely fortunate to call Johnson my home, and I look forward to every day that I get to work with our great faculty, students, and community.  I am looking forward to another great year as a Johnson Jaguar!
