School Reviews

I have three children at this school. Each one of my kids has unique strengths and challenges with respect to their educational needs. I have loved the way this school has catered to these needs. The kids are with the same pair of caring teachers for 3 years, allowing them to develop a strong relationship and to be understood. We have had a wonderful experience at every classroom level.
