Antonian College Preparatory High School in San Antonio, TX

Welcome to Antonian!

Whether you’re a current or prospective student or parent, an alumnus, or just stopping by, I would like to welcome you to Antonian, “a place called home.”  

Serving the students, families, and stakeholders as the educational and spiritual leader of Antonian is an absolute blessing.  As the largest Catholic school in the Archdiocese of San Antonio, the administrative team, faculty, and staff have a shared co-responsibility in the success of our campus, and as such, it is our philosophy to prepare our students for the world they will be entering when they leave Antonian.  That preparation is based on the total formation of each of our students—academic, athletic, social-emotional, and spiritual.  

If you are interested in finding your home at Antonian, or if it’s been a while since you have visited our campus, I encourage you to give us a call, come take a tour, and catch a game under the lights on a Friday night or on the hardwood.  Join us on a walk among the Apaches.  When you do, you are encouraged to wear the red, walk the walk and make a difference.

God Bless and Roll Tribe,

Antonian College Preparatory High School
