Why St. Mary's?

“My experiences at St. Mary’s have been incomparable. No other school has a closer community than here. Everyone knows everyone’s name. Even the teachers know every student and how each one of us learns. It is this close attention and family atmosphere that have helped me to achieve all that I have during my four years here. I can look back at each step in the National Merit process and recall how Mrs. Klimpel proofread an essay or Dr. Muentnich helped me pick a college major. Everyone here is connected, and I am confident these connections will last throughout college and the rest of my life. The opportunities at St. Mary’s are immeasurable.”  - Tony Puricelli, National Merit Finalist and Valedictorian of the Class of 2010

"...this place is like no other. My son is flourishing and is so happy here. What happens here is so simple, yet so profound. My son is standing tall and growing into a young man. The care and understanding he has received here is remarkable.  I could not be any happier."  - Dana Kramer, Parent of Alex, Class of 2014
