Welcome to Trinity High School!

Dear Family,

High school is an amazing time, and choosing the right high school is one of the most important decisions you will ever make. At Trinity High School, we prepare our students beyond the mastery of skills and acquisition of knowledge alone. We help students develop a sound work ethic, self-discipline, and high ideals to help them achieve their best throughout life.

As a Catholic school, we believe our students are best prepared to lead happy and fulfilling lives directed by their faith. Our mission as a Catholic school is aimed toward uplifting our students to seek the best in life by seeing everyone as children of God in the Catholic tradition. It's a simple principle, but one that makes all the difference!

We encourage you to visit Trinity, walk the halls, and speak with the students and staff.  Experience what Trinity is all about.

Faith, Scholarship,
& Character

These are the foundation of our entire program.


 A life of faith is one with direction toward something greater than ourselves.


The principles of good scholarship translate to a sound career achievement.


Our character is a matter of who we are deep down inside. It's what we do when no one is looking.
