Welcome to St. Mary's Prep Admissions! 

​

St. Mary's is a co-divisional, Catholic high school focused on providing an exceptional high school experience in a Christ centered environment.

​

Our admissions office is here to help your family get to know OLSM by providing you a personal admissions experience tailored to your child. We look forward to welcoming you to our school and to showing you what it means to be a young man or young woman of Orchard Lake.

God Bless,
