Great staff, diverse student body, Christ-centered education, sports (basketball, volleyball, track, soccer, etc.), music lessons and more. Both of our children have (or will have) attended from pre-K through 8th grade.

One of the best Pre-k programs I have seen. Easy to make the kids feel like a big kid when the Pre-k program is part of the larger school.
