THE TEAM

Thorne is governed by a Board of Trustees which makes policy level decisions that guide operations to ensure the fulfillment of Thorne’s mission. All of Thorne’s Trustees volunteer their time and contribute their talents in ways that best help Thorne connect youth to nature. 

Thorne’s programs are managed and implemented by an experienced staff of nonprofit professionals and environmental educators. Thorne maintains a small year-round staff and hires more than 30 seasonal instructors for its camp each summer.
