Alumni Reviews Review School

Description

Class of 2023

Stony Brook
The sizes of classes are quite small, which I think is unique because it allows for more concentrated lessons and more one one-on-one teaching. The smallest class I've been to only had three other students. . .

Class of 2003

Fordham University
There is an amazing family atmosphere at Knox that is unlike any other school I attended. I highly recommend the school for any parent looking for a boarding school because your child will be cared. . .
