School Reviews

I school choice my 2 boys to this school. You cannot find a better group of people and the sense of commitment and responsibility is found everywhere. It's a small school so you get to know the teachers and they know your kids. I have committed to drive (no bus for school choice) 20 minutes at least 2 times daily sometimes 4 and it's worth every drop of gasoline!
