Trinity’s Belief Statement

Christ is the reason for this school.

He is the unseen but ever present teacher in its classes.

He is the model of its faculty

and the inspiration for its students.


                                                                       John J. Findlater


The Catholic Identity of Trinity is a priority for the students, administration, faculty, staff, advisory board, and parents in the school community.

The Catholic Identity at Trinity is present in the physical environment of the school, stressed in Faith Formation programs, evidenced by the education in faith that crosses all curricular areas, expressed through Sacramental life, and demonstrated through meaningful experiences of the Catholic community.
