St. Mary's Preparatory is a co-educational, Catholic, college preparatory high school with a Polish-American heritage in the Detroit suburb of Orchard Lake Village, Michigan. Its mission and message is "God, Family and St. Mary's." Overview St. Mary's was founded in 1885 on Detroit's east side on the corner of Forest and St. Aubin by Rev. Joseph Dabrowski as a school for Polish-American boys to train for the priesthood. The school moved to the 125 acre (0.5 km²) campus of the former Michigan Military Academy on the shores of Orchard Lake in 1909 and is still there today. St. Mary's offers a college preparatory education. The campus is shared with SS. Cyril and Methodius Seminary and contains some offices and classrooms for Madonna University of Livonia, Michigan. The Felician Sisters from Livonia, Michigan have served the Orchard Lake Schools since 1935. Since 2020, St. Mary's Preparatory opened admissions to girls. Academics St. Mary's academic program is designed to meet the basic entrance requirements for any college curriculum. Requirements for graduation are: four years of theology and English; four years of mathematics; three years of science and social studies; three years of foreign language; and a semester each of computer programming, computer applications, physical education, health, fine arts, and speech. Students are required to fulfill 28 credits for graduation. Over 60% of the 90 different courses offered by St. Mary's Prep from grades 9-12 are at the honors and AP level. Although students need not be Catholic to attend St. Mary's, all students are educated in the Catholic tradition. This tradition includes four years of theology in the classroom as well as attendance at Mass twice weekly. Class retreats and other activities are available for students. The school chaplain and many campus priests can guide students regarding their individual programs. 100 percent of St. Mary's graduates who apply to college have been accepted. A full-time guidance counselor assists students in selecting colleges and universities. The school held the national record for most students from one year to go to the U.S. Naval Academy (4). Students may enjoy walking to classes as the classes are located in different buildings, so the outside walks offer fresh air and scenic views of the campus and Orchard Lake. St. Mary's Preparatory is fully accredited and licensed by the State of Michigan's Department of Education, the Michigan Non-Public Schools Accrediting Association (MNSAA), and is a member of
