Better Education. Brighter Future.

Alumni

Trinity Catholic High School celebrates the venerable traditions of Mercy High School (1948-1985), St. Thomas Aquinas High School (1954-1985), Rosary High School (1961-2003), St. Thomas Aquinas-Mercy High School (1985-2003), and Trinity Catholic High School (2003 – present). The legacies of each of these wonderful schools have merged to create our Trinity Catholic community.

We cherish those who have paved the way for Trinity Catholic, and we hope that the alumni of each of these schools keep in touch. All alumni have several options to get involved and reunite throughout the school year. Check the Trinity website for upcoming reunion events and other alumni events. See the Golf Tournament, Auction, and Booster Club sections for more information.



Help us keep you informed by calling the school to update your alumni profile. Keep an eye out for our alumni newsletters and special information.

For any questions about upcoming events, how to make a contribution to the school, or if you have information about upcoming reunion events or other important class information, contact the Advancement Office:
