In 1992, Holy Trinity School became the first elementary Catholic school in the Bay Area to become accredited through the Michigan Non-Public Schools Accrediting Association. Each year the staff and parents work together to improve the school as it continue to "Reach for the Best."

Throughout the history of Holy Trinity School, the parents have been supportive of Catholic education in all capacities. The school has a very active Booster Club and Home and School organization. The School Committee serves in an advisory capacity to the principal and pastor. An endowment fund was established in 1996 in order to develop a sound financial base for the future of Holy Trinity School. The board of trustees have been instrumental in promoting the endowment fund.

Holy Trinity is a family of families who "Reach for the Best."
