Welcome to Holy Trinity Catholic High School. Thank you for taking the time to explore our website. For the past twenty years, the mission has been to form the "Christian Leaders of Tomorrow." We believe the most important outcome for each member of the Holy Trinity community, is a personal relationship with Jesus Christ, which results in the continuous formation of the whole person, the development of God-given talents, and a commitment to a lifetime of success and service to others.
"Be it known to all who enter here that Christ is the reason for this school. He is the unseen, but ever present, teacher in its classrooms. He is the model for its faculty and the inspiration of its students." -Author Unknown
