Building Excellence

Brothers of the Society of Mary (Marianists) brought Catholic education to San Antonio in 1852 when they opened St. Mary’s Institute. Continuing the legacy, St. Mary’s University, an outgrowth of the brothers’ first educational undertaking, is committed to the Marianist ideals of academic excellence, ethical commitment and service to the community.

The Marianists who established St. Mary’s are members of a religious order known as the Society of Mary, founded in 1817 by Blessed William Joseph Chaminade, a French priest who nurtured an idea of forming lay and religious societies that would re-energize the Christian faith in the post-French Revolution era. Four French Marianist missionaries travel to Texas to open a school at the behest of Galveston Bishop John Mary Odin. In May 1852, three of the brothers — they will later be joined by the fourth — all dressed alike in black suits with starched white collars, step off the Indianola stagecoach to get a glimpse of downtown San Antonio, where they will establish their school.

Hard work and proper comportment are expected of students inside the classroom and at play. The boys are closely supervised by Marianist teachers and administrators.
