Located in the heart of Waukesha, Mill Creek Academy never sets limits on how much your child can achieve. We shape instruction to build on the strengths and abilities of each child and make Moral Focus lessons part of every school day. As a result, our students thrive. In fact, a study done by Stanford University reveals that National Heritage Academies partner-school students gained the equivalent of three-and-half-months of additional learning compared to their peers.

"My children love coming to school and have made new friends, built relationships with staff, and have gained new knowledge and skills. As parents, we love the communication and community events. It’s great to see staff outside of school and the kids enjoy these events. We couldn’t be happier with our choice to move them to Mill Creek!"
