School Notes

  • Since 1958, Trinity Catholic has served as a co-educational, Christ-centered learning environment focused on the body, mind and spirit of our students. A college preparatory environment, our thousands of alumni have gone on to leading universities nationwide, into career paths in business, vocations, the arts and sciences. Over 97% of our graduating seniors go on to renown colleges and universities across America. From its inception as Stamford Catholic High School, a focus on nurturing student values has existed; their character and integrity are developed alongside self-discipline, service and community citizenship. At Trinity, we foster an environment that challenges students, inspires them and along with supportive parents and their families helps form whole and contributing citizens of an increasingly global community. Currently undergoing its third major renovation, Trinity is preparing for the next generation of twenty-first century learning and formation.
