The Davey Tree Expert Company

The Davey Tree Expert Company is an employee-owned provider of tree care and environmental services across North America. Founded in 1880 by John Davey, who pioneered the concept of tree surgery, the company has been in operation for more than 140 years and describes itself as North America's oldest and largest employee-owned tree care company. Employees are able to hold a stake in the business, and the firm emphasises professional development and careers in the field and beyond.

Its work covers arboriculture, urban forestry, plant health science and environmental consulting. Services are organised around four lines: residential tree care, focused on the health, safety and condition of trees and landscapes; commercial grounds management for business clients; vegetation management for utility companies; and environmental consulting and natural resource services. The approach is research-driven and science-based, delivered in part by ISA certified arborists and other field experts.

The Davey Institute, the company's research and innovation arm, advances plant health science and supports professional development. Technical domains within the business include tree surgery, utility vegetation management and scientific tree care, serving customers in the utilities, commercial grounds management and residential property care sectors. The company's stated legacy is one of environmental stewardship in the urban forest.
