OUR CORE VALUES
Trinity Catholic High School, guided by a philosophy based on our Catholic faith and the teaching of Christ in the Gospels, strives to educate young women and men through a comprehensive program of academic excellence.
Trinity Catholic High School, recognizing the uniqueness and diversity of individual talent, intellect, style, and ability, teaches students to think critically, live virtuously, and serve joyfully.
Trinity Catholic High School enables students to be transformed into moral, prayerful, responsible men and women who, in turn, transform our Church and the world as mature Christian citizens who respect the diversity and sacredness of God’s Creation.
OUR HISTORY
Mercy High School opened in 1948 in University City and was staffed by the Sisters of Mercy. The school served the Catholic community of the central city and county areas until it merged with St. Thomas Aquinas High School in 1984.
St. Thomas Aquinas High School opened in 1954 at Sacred Heart Parish School in Florissant. It moved to the Dunn Road location in 1958. The school was named after the 13th century philosopher who is the patron saint of Catholic education. St. Thomas Aquinas-Mercy was consolidated with Rosary to form Trinity Catholic High School in 2003.
Rosary High School was founded in 1961 by the Catholic Schools System of the St. Louis Archdiocese, in collaboration with the School Sisters of Notre Dame. It has been located at 1720 Redman Road since it opened. The high school was dedicated to Mary, the mother of Jesus Christ, and our Lady of the Rosary. Rosary was part of the Trinity Catholic High School consolidation with St. Thomas Aquinas-Mercy in 2003.
