School Reviews
5 1/1/2020
I cannot say enough good about this school. The teachers are just wonderful. The academics are tougher than most public schools, but the teachers challenge the kids to do their best & they typically respond. They are a college prep school, but they want the kids to be well rounded so they require an hour and a half of sports participation DAILY. Even if your child isn't enthused about sports, the idea is to find them something they can do to get some exercise from tennis to sailing/crew. The grounds are gorgeous and very homey feeling. They allow for all kinds of music and art classes and having many clubs for the kids to join-or start! They're inclusive & really try for ALL the kids to fit in. Virtually no bullying in the place and a real effort to make everyone welcome.

Excellent school and program. Teachers are amazing - lots of clubs and activities for the students. Athletics are very good and along with traditional offerings, there is sailing and crew. Located right on the Corsica River.
