On January 14, 1879,Pope Leo XIII authorized the establishment of a seminary dedicated to training priests forPolish immigrant communities in the United States, following a petition by Rev.Leopold Moczygemba.[4]
Initially known as "The Polish Seminary," the institution was officially founded in 1885 byJózef Dąbrowski, who became its firstrector. It was originally located at 4671 St. Aubin Street in Detroit. Due to expanding enrollment, theseminary moved to the former campus of theMichigan Military Academy in Orchard Lake Village in 1909 under the leadership of Rev. Witold Buchaczkowski.[5]
In 2020, St. Mary's transitioned to a co-divisional model by admitting female students. Classes are taught in single-sex classrooms, while extracurricular activities, clubs, sports, and arts programs are co-educational.[7]
More than 60% of the school's 90 courses are offered at Honors orAdvanced Placement (AP) levels.[9]
St. Mary's is accredited by the Michigan Non-Public Schools Accrediting Association (MNSAA), the Archdiocese of Detroit, the Detroit Catholic League, Oakland Schools Consortium, and theMichigan High School Athletic Association (MHSAA).[10]
