"Christ is the Reason for this School..."

Christ is the reason for Trinity Catholic, thus the Catholic faith is the foundation for all that happens at our school. At Trinity, all walks of life are able to learn from the Catholic faith and use those lessons to become better citizens. 


To ensure that our mission of graduating students grounded in Christian values is upheld, all students take eight semesters of religious instruction. These courses correspond to the social and personal issues that high school students face everyday. 


Trinity is blessed to have its very own Chapel built into the school. The Chapel is open for Mass one day a week. Students and faculty may also reserve time in the Chapel for individual prayer services, reconciliation, and other spiritual needs.
