What is the concern regarding the size of the school - too small or too big? Personally I find that range to be a happy medium.
The swim program at Peddie has swimmers of all levels, though non without previous swimming experience. Several will swim in college but many don’t. The kids on the team are very supportive of each other - I think this is true of the schools community in general. The expectation is that you always show up and do your best but isn’t that true of all teams?
