Aquinas High School opened in the fall of 1957 following the merger of Boys’ Catholic High School and Mount St. Joseph Academy. Reverend Ralph E. Seikel served as priest moderator and Monsignor Daniel J. Bourke oversaw operations and finances as the school’s president. Six Marist Brothers taught the 132 boys on the south end of the building. Six Sisters of St. Joseph taught the 110 girls on the north end of the building.

Today, Aquinas High School is a college preparatory, co-educational school with 230 students enrolled in grades 9-12. The student population is approximately 58% male, 42% female, 19% minority, and 80% Catholic. Students come from more than 24 different Zip Codes located in 6 counties and 2 states.

Aquinas High School is accredited by AdvancED—Southern Association of Colleges and Schools Council on Accreditation and School Improvement (SACS-CASI). The school is governed by the policies and procedures of the Catholic Schools Office within the Diocese of Savannah. At the local level, an Advisory Board and various committees work with the school’s administration to advance the mission of the school.
