The ISLE Society is a community of young professionals in their 20s and 30s who stand In Support of Leadership and Education. ISLE Society events engage young professionals from around greater Boston who gather on Cathleen Stone Island and on the mainland to make new friends, network, and have fun while connecting over a good cause. The ISLE Society aims to further the mission of Cathleen Stone Island Outward Bound School by engaging the next generation of supporters and philanthropists.
Members are invited to exclusive events and granted special access to Cathleen Stone Island Outward Bound School events (see a full list of benefits below). Join today to become part of a like-minded group of young professionals who are passionate about supporting our community's young people.

Membership
Make a one-time membership donation—or make it monthly—on our donation page!
Committing to a membership-level donation early in the year helps build our young professionals community, and you can then take advantage of membership perks during the year!
Or, you can build your membership throughout the year with our new give-and-get format. If you secure a raffle item for any CSIOBS event, secure peer-to-peer fundraising for the 4K, or have your company sponsor an event, the value will count toward your ISLE Society membership.
Members have an incredible impact on our work with students. Additionally, once considered an annual member, they receive the perks outlined below in recognition of their dedication to Cathleen Stone Island Outward Bound School.
