As with all kids, there are challenges that arise and the Lighthouse School always meets those challenges head-on with kindness and compassion and a fundamental understanding of the individual learning process for each child.
The school's philosophy of addressing a child's mind, body and individual spirit, while teaching and supporting skills for critical thinking, creative problem solving, and the navigation of one's social-emotional life, has allowed her daughter Clementine to thrive in her academic experience. "We couldn't have asked for a better school for our daughter, anywhere, let alone on this little island! We love our Nantucket Lighthouse School Community."
