I have seen my child grow by leaps and bounds at St. Joe. I have watched him go from a freshman who knew no one to a sophomore with a core group of friends that support him no matter what. My son's also gone from a kid who played zero sports to a Varsity athlete at SJ. I love this school.

St. Joseph High School is one of the greatest schools you could choose for your child to grow and learn. The students at St. Joseph are incredibly empathetic and truly enjoy serving with and for others. They are more than just students - they play sports (on championship teams!); they study hard; they travel on immersion trips, and they truly enjoy spending their days at school.
