Campus & Facilities

St. Thomas Aquinas has two campuses located .5 mile apart.


The Upper School sits adjacent to the Church and houses grades 3rd - 8th. It includes a gymnasium, three science labs, an art room, drama room, and a 3-acre athletic facility for football, baseball, softball, and soccer. The St. Dominic Building at the Upper School houses the performing arts classrooms, tutoring labs, and enrichment programs such as the robotics lab, and the new video production studio. The Church also serves as an integral part of our campus as the students and faculty attend Mass weekly and participate with the community-at-large on Holy days and Feast days.



The Lower School, seven blocks to the north of the main campus, houses grades PK-2nd. The Lower School includes a chapel for weekly Mass and prayer services, gymnasium, library, drama and art rooms, outdoor science areas, and playground.
