Sculpture Saint John has a volunteer base of more than 125 people.

Volunteers are involved from the first step of preparations for each symposium, acting as board and committee members; helping organize special fundraising, education, and sponsorship events; overseeing merchandise; facilitating marketing and communications; and developing outreach strategies for the public. Throughout the four-week symposium, volunteers are on site, greeting and providing guided tours to visitors, and assisting artists and interns with on site support.
