TREE Fund Board of Trustees 2025
Our board members share a passion for healthy trees in our communities and healthy growth in the tree care industry. Our all-volunteer, working board represents a broad spectrum of expertise in commercial, municipal and utility arboriculture, academia, research, manufacturing and communications. TREE Fund embraces diversity to ensure that a range of perspectives and experiences are incorporated in the work of its board; arboriculture experience is not required.

TREE Fund Liaisons
TREE Fund Liaisons provide a vital link to allied organizations in the fields of arboriculture and urban forestry – primarily local ISA Chapters. Liaisons are a critical communication conduit between TREE Fund and the industry organization they represent. Liaisons “friendraise” for TREE Fund by sharing TREE Fund news and research results with their organization, working a TREE Fund booth at their annual Chapter conference, encouraging their Chapter and its members to support TREE Fund, and connecting people in their circle of influence with TREE Fund and its activities.
