St. Thomas High School is a Roman Catholic college preparatory school for young men in grades 9-12. The school was founded by the Basilian fathers in the spring of 1900 with the mission to provide secondary education strongly rooted in the teachings of the Catholic faith.
Teaching of Goodness, Discipline, and Knowledge is the tradition of the Basilian Fathers and the sacred mission of St. Thomas (STH). These three words emulate the STH experience for students, faculty, and families.
Throughout the four years of high school, STH boys grow into men who think critically, communicate effectively, serve faithfully, and are prepared to excel in college and life.

St. Thomas has been an excellent school for my 3 boys. My oldest son felt very well prepared for college. My middle son feels supported and cared for by his coaches, teachers, and the school faculty. My youngest son has been excelling in his Advanced classes. There is a place for everyone at STH.
