School Notes

  • School Motto: To inspire and empower young men and women to thrive while leading meaningful lives rooted in the teachings of Jesus Christ.
  • School Mascot: Apache
  • Antonian was established in 1964 by the Archdiocese of San Antonio with the support of the pastors from twelve northside parishes and was originally staffed by the Brothers of the Christian Schools. Antonian retains many of the innovative practices attributed to St. John Baptiste De La Salle, including the integration of religious instruction with academic subjects, well-prepared teachers with a sense of vocation and mission, and the involvement of parents. Originally a school for boys, Antonian transitioned to being a co-educational school in 1989.Preparing students academically, socially, and emotionally for higher education and life demands an environment reflective of the real world. The real world is comprised of men and women, and Antonian graduates are prepared to interact and work with members of the opposite sex both in college and classrooms and in the workplace. This Antonian dynamic empowers students to grow as both individuals and members of the community.
