Teresa Cuellar-Hernandez - Principal
Hey, Mustangs! My name is Teresa Cuellar-Hernandez, and I am excited, honored, and humbled to serve as the principal of John Jay High School. This is my 25th year in the Northside Independent School District. I started my teaching career right here at John Jay HS, opened up Warren HS, served as an assistant principal at Marshall HS, vice principal at Stevens HS and most recently served as the John Jay Science and Engineering principal.

To our students: I cannot wait to see all of the wonderful things you do. I will work to make your experiences purposeful, meaningful, and enjoyable. My hope is that you each take advantage of the academic opportunities, the support systems that are in place for you, and get involved in your high school experience through the many extracurricular organizations available on campus.

My vision is to ensure that all students achieve both academically and socially beyond personal expectations while experiencing an outstanding and enjoyable education. I want students to be exposed to opportunities like no other and make each of your educational dreams come true. We can accomplish this together. I truly BELIEVE in each and every one of my students.

One TEAM! One Vision! We are THE MUSTANGS!

    Academic Dean

    I am Theresa Long, your academic dean at John Jay High School.  I am excited to be in my second year on the Jay admin team.  

    This is my nineteenth year in education; the first thirteen years I spent at Harlandale High School where I served as a math teacher and math department coordinator.  I taught all levels of mathematics from Algebra I through AP Calculus.

    After high school, I moved to Austin to attend the University of Texas where I earned my bachelorโ€™s degree in mathematics and a teaching certificate.  After moving back to San Antonio I began teaching and attending UTSA at night to earn a masterโ€™s degree, also in mathematics. 

    I have been married for fourteen years to my husband, Charles.  We have one daughter, Evelyn.  We love to spend time with our extended family and enjoy playing numerous board games and building with Lego bricks.
