We never set limits on how much your child can achieve. At Mill Creek we create endless opportunities for your child to become their best. 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 students gained the equivalent of three-and-half-months of additional learning compared to their peers.
