Trinity High School is a diocesan, Catholic, co-educational community, fostering mutual respect among students, faculty, staff and parents.
Its ministry is to teach the Gospel message, build fellowship and effect change through service to others.
Catholic values permeate the school's college preparatory curriculum for the maximum development of the whole person.
As a Catholic school and caring community, we are committed to the following objectives: to make students aware of peace and justice issues and provide them with motivation and empowerment to become involved; to offer a college-preparatory program that stimulates intellectual, creative, emotional and physical growth and develops critical thinking skills; to encourage in students a healthy respect for self, family, school and society while fostering caring relationships within the Trinity family; to maintain a strong campus ministry program which will infuse into all aspects of the school a sense of Catholic values and traditions, provide varied and age-appropriate religious worship experiences, all leading to an enhanced spiritual and moral development in students; and to provide an ordered and disciplined environment which facilitates the development of the whole person, while encouraging all individual gifts and talents.
