The Priory was founded in 1957 by a group of seven Hungarian Benedictine Monks from Saint Martin's Archabbey in Pannonhalma, Hungary.

[3] The school began on an 18-acre (73,000 m2) ranch and over the years has expanded significantly to the point that the campus now encompasses some 50 acres (200,000 m2).

In the early 1990s, the school began admitting females to the day program; the first coed senior class graduated in 1995.

[citation needed] The Priory offers football, cross country, volleyball, tennis, water polo, soccer, basketball, lacrosse, swimming, track and field, and baseball.

[4] In 2000, the girls' volleyball team won the state championship for Division V. The school competes in Central Coast Section (CCS) post-season competition.
