We moved to the area because we had known of St. Peter from out of state. If life was going to lead us to Chicagoland, we knew we would want our kids at St. Peter. And wouldn't you know it, a year later we were making the move to Chicagoland for work. We had high hopes when we enrolled our kids. Our experience has far exceeded what we hoped it would be. It has been remarkable. The leadership, disciple making, academics, music programs, sports, and so many other things make this place special. I wish everyone could have the experience our family is having!

Sending the kids to St Peter for their education was one of the best parenting decisions we've ever made. Currently they are in 6th and 3rd grade. St Peter provides a classic education focused on mastery of concepts, accountability, and measured results which differs from our children's experience at the local public school. St Peter also provides students tangible opportunities to make an impact via extra-curricular activities like sports, performing arts, and student council. These opportunities are accessible to all students, unique to a smaller school, yet still with high expectations for all to push themselves to do their best. Since returning to St Peter school, our weekly day-to-day has been abundantly fuller and more aligned with our family's core values. St. Peter is a great place to be!

Choosing St. Peter has been the easiest thing my husband and I have done for our children! We love the community, the staff/teachers, and the feel you get when you walk in the door. You don't get that at every school, so it makes it even more special! We are also alumni, so it was no question where we'd send our children. Our best years were at St. Peter, and we hope that is the same for our 3 little ones.

St. Peter is such a wonderful place to be. The current administration is top notch, and the teachers are wonderful. Faced with the choice to move to the top rated public schools in the area I am so glad we decided to keep our children here in such a thriving, welcoming community!!
