School Reviews

Our daughter was in the infant room and MDO rooms at Countryside Montessori, and we couldn't have asked for a better place to send her! The staff truly loves and values the children, and the activities they planned greatly challenged her. We watched her grow immensely developmentally, mentally, and emotionally while at Countryside. She would come home singing new songs and practicing new skills she learned at school, and she obviously loved her teachers. Even after she left the infant room, those teachers would still check in on her and showed they cared. The teachers were always willing to spend time chatting with parents at the end of the day, and were incredibly communicative during the day. They even created a portfolio complete with crafts and pictures of our daughter to give us when she left. You know you've found a good place to send your child when you never worry about her while she's there, and Countryside is definitely that place!
