Welcome to the Wisconsin Arborist Association (WAA)

The WAA has been dedicated to our mission "To improve the practice of arboriculture and increase public appreciation of trees and urban forests."  Over the years, this organization of commercial, municipal, utility and academic arborists has grown to include over 700 members with the like-minded goal of taking care of Wisconsin's trees.

These members service Wisconsin by providing private and public arboriculture services, research and outreach activities. The WAA is a chapter of the International Society of Arboriculture which has representation in over 30 countries.
