The Cornerstone School was incorporated in December 1985 as a non-profit organization with the goal of meeting the growing need for a non-traditional private preschool and elementary experience in the seacoast region of New Hampshire.

We are committed to a school which is small enough to maintain a feeling of community. Thus we can maintain individual attention and foster the development of each child in our care.
