There is a sense of community here that is unlike any other school. I find joy in noticing students helping each other both in and out of the classroom. Children of all grades have deep conversations with adults in many different ways – from academic to social. The atmosphere is cheerful and studious and reflective of the school values and mission statement. CRS is committed to honoring the joy in childhood and does it well.
