Marianapolis gave me a unique high school experience. Since it was a boarding school I was able to meet many people from all over the world even while being a day student. It prepared me for college and helped me develop a good sense of time management.

There is not better place for your child than Marianapolis. A wonderful school with many opportunities (academic, sports, art, social) for their students and an amazing community. Marianapolis Prep is certainly the place that you want for your kid during their high school experience.

I have had 2 children attend Marianapolis and the experience is second to none. I praise every single aspect of the school and both children have thrived. They challenge and bring a student to a level one would never think of. LOVE LOVE LOVE this school

Marianapolis is a wonderful school and my son has grown academically, athletically and socially because of the dedicated faculty and staff. As we get ready to send him to college we are confident that he is well-prepared for any challenge that he may face. Thank you MPrep!
