Holy Trinity Catholic School, which opened in 1954 in Robinson Township west of Pittsburgh, Pennsylvania, served Catholic families of the West Hills, teaching that each child is a unique creation of God with spiritual, intellectual and social needs. The school worked in partnership with parents, faculty and the parish community to give students active minds, compassion for others and the courage to act on their faith. In 2019 it merged with St. Malachy School to form Archangel Gabriel School, which uses the former Holy Trinity campus in Robinson.
