The sense of community and pride at this school is truly incredible. Once a Titan, Always a Titan. Class of 2012.

I would certainly recommend Holy Trinity because it has great leadership, a very talented teaching staff that encourages their students and builds on their strengths. Father John is wonderful and caring. He even went to see the talented basketball team win the championship along with a very large group of students cheering on their fellow students. Big talent at this school!
