When shopping for our house, my son loved Trillium Creek. The staff gave us a tour of the award winning designed school. He was challenged all of his years there by fantastic teachers. There definitely was a promoted social group bond with the students with regular activities. My son was always happy to go to class and still has his great friend group. Close Quote
