Saint Louis Priory School is a faith-centered, Catholic, independent day school for boys in Grades Seven through Twelve offering a nationally recognized accelerated curriculum designed to qualify its graduates for admission to distinguished colleges and universities and to prepare them to undertake their continuing studies with success. The school represents the primary work of the Benedictine Monks of Saint Louis Abbey, founded in 1955 by Monks of Ampleforth Abbey in York, England. In addition to one of the strongest college preparatory programs in the area, the school seeks to ground young men in the knowledge and practice of the Roman Catholic faith, supported by the highest percentage of religious teaching faculty of any Catholic high school in Saint Louis.

In addition to providing a comprehensive program of studies in the humanities, sciences and theology, the curriculum requires participation in athletics, fine arts, community service and a senior thesis. Nearly 100% of the students undertake college-level work in their last two years, and many receive college placement and credit through the College Board Advanced Placement (AP) Program offered in over a dozen subject areas. The school is located on a 150-acre campus in West Saint Louis County. Over 30% of the student body receives financial aid, amounting to over $1.5 million this past year alone. Father Gregory Mohrman, O.S.B. is Headmaster. Dr. Jared M. Rashford is Principal.

Summer Camps

  • Aestas: The Summer Program at Saint Louis Priory School
    Monday, Jun 06, 2016 — Friday, Jul 01, 2016

    Forge new friendships as you pursue transformational academic, artistic, and athletic opportunities with skilled instructors in a dynamic environment. Hone creativity and problem-solving skills through a holistic approach, merging the classic and modern as you sharpen deductive reasoning skills in the mold of Sir Arthur Doyle’s hero, Sherlock Holmes. At the same time, you’ll incorporate modern forensic techniques made famous by the BBC’s Sherlock.
    AESTAS runs morning to mid-afternoon June 6-July 1. Priory's summer sports camps offer a summertime extension of the Rebel athletic program, where young athletes learn the keys to success in sports and in their personal lives. Coaches emphasize the pleasure of playing each sport while developing athletic skills and good sportsmanship.

    Both Aestas and our sports camps are held on Priory's beautiful 150-acre campus in West St. Louis County.
