Cos Cob School Reviews

By a Parent on

My daughter is in K at CCS and we love it.  What I love about CCS that makes it different from the other schools in Eastern Greenwich, is that children are still encouraged to learn and develop and there is still a TAG program but there is a great deal more stress on being community minded and giving back to society than I have seen in the other Greenwich schools and my job keeps me traveling around OG, Riverside, NMS and ISD a great deal.

By a Former Student on

All the teachers and students are nice. I learned a ton of things at CCS.
