"Believe that you can do it 'cause YOU CAN do it" - Bob Ross
This is my 27th year in education and my 27th year in the Northside Independent School District. John Jay is where I began my teaching journey, and today, it remains my home. I’ve had the privilege of serving across several NISD campuses—opening Warren HS, serving as an assistant principal at Marshall HS, vice principal at Stevens HS, and most recently as the principal of the John Jay Science & Engineering Academy. It is my honor serving the amazing Mustang community.
John Jay is more than just a school—it’s a place rich with history, tradition, and pride. It is my life’s work, and I am deeply committed to our mission of student success. I believe in our students and their potential. Every student deserves to be challenged, supported, and celebrated for their achievements—both academically and personally.
To our students: I can't wait to see the incredible things you’ll accomplish. My goal is to ensure your high school experience is meaningful, purposeful, and filled with opportunities. Whether it’s in the classroom, on the field, or through extracurricular activities, I encourage each of you to get involved, dream big, and strive for greatness.
Together—with the support of our dedicated staff, families, and community—we will make this a remarkable year. I truly believe in each and every one of you.
Let’s make it a great year, Mustangs!

Jay Community, it is an honor and a privilege to serve as your Associate Principal. I have been in education for 15 years, with the last 12 proudly spent in Northside ISD. During my career, I’ve had the opportunity to serve students as a History and Physical Education teacher, Basketball and Track coach, Student Success Advisor, and most recently as an Assistant Principal before stepping into my current role as Associate Principal.
My mission is to give back to this community by building up those around me, encouraging our students to be the best versions of themselves, and preparing them to face the challenges that high school brings. At John Jay, we strive to teach more than academics — we aim to help students navigate tough decisions, make positive choices, and build meaningful relationships that empower them to positively impact their communities long after they leave Jay.
Thank you for trusting us and allowing us the opportunity to lead all of our Mustangs to success.

Theresa LongAcademic DeanI 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 bachelor’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 master’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.
