This program was the most incredible experience that my daughter has had academically and socially. The teachers, the Maine Coast, the Outward Bound meets challenging academics was by far life changing. Her view on the world has opened up and her appreciation for the world around her and the environment is beyond amazing. She became her most authentic self and I am so proud of her to have made the decision to apply, accept and meet the demands of this program. I would recommend this to anyone with a rising Junior.
