Since 1986, Colonial Tree Service has served Waukesha County and surrounding communities. We understand how well-maintained trees and shrubs add tremendous value to your landscape and benefit the community overall.

We are professional arborists that strive for excellence in all we do, whether it is caring for trees or working with clients.  Our company was built around core values that include honesty, integrity, safety, dependability, and great service.

At Colonial we require an ISA Certified Arborist and Certified Treecare Safety Professional (CTSP) on every job to ensure all work is completed in accordance with industry standards and best practices.  We use state of the art equipment and employ crews that are professional in appearance and performance. 

Our team remains engaged in the field of Arboriculture and Urban Forestry through continuing education and active memberships with the International Society of Arboriculture (ISA), the Society of Commercial Arboriculture (SCA), the Tree Care Industry Association (TCIA), and the Wisconsin Arborist Association (WAA).
