Get Started

At Aquinas Institute of Theology, we are proud that our school bears the name of the great Dominican saint and doctor of the Church, St. Thomas Aquinas. Students are provided with unique access and engagement with our Dominican heritage in the 800-year-old rich, intellectual tradition of the Order of Preachers. We provide students with a close-knit community, excellent academic programs, and spiritual formation. 

Situated adjacent to the large and beautiful campus of Saint Louis University, students also have access to all the resources of a large Jesuit research university. 

At the heart of each program is the unique Dominican approach to education that holds as its primary purpose a search for Veritas, the One who is Truth himself, Our Lord Jesus Christ.
