Great community! A very warm and welcoming school. Close Quote

by a parent
Wednesday, April 9, 2014

Dedicated, experienced teachers. Children are pushed to excel and encouraged to learn. Teachers expect parents to participate in educational process. Very happy place. No bullying, but can be a bit cliquish among students whose parents grew up together in the community. New arrivals are not immediately welcomed into community. Fairly anti-military sentiment among parents and some teachers. Close Quote
