SS. Cyril and Methodius Seminary in Orchard Lake to close next year The Detroit News View Comments An Oakland County seminary that has trained generations of Polish priests over its 136-year history will close next year. Officials with SS. Cyril and Methodius Seminary in Orchard Lake announced Thursday the school will cease operations at the end of the 2021-22 academic year. The Board of Regents for Orchard Lake Schools, which shares a campus with the seminary, cited several reasons for the decision, including "declining enrollment caused by demographic changes in the United States, more vocational options in Poland, and recent policy changes that do not allow Polish seminarians to transfer between seminaries."
