Helping Define The Science Of Tree Surgery Since 1880

Company founder John Davey believed tree care is a science, and the original business plan included a technical development and research department to bring the leading science of the day to our client's property via our field service teams. 

This vision is woven into the very fabric of our company with a commitment to innovation that still drives the next generation of plant health care strategies as well as new business opportunities for Davey and our partners.

Our scientists and technical advisors guide field service teams in diagnosing and prescribing the best products, application procedure, and pest and disease cultural practices to be used at the client site.

Davey technical teams are staffed with experts in a particular aspect of plant care and a specific geographic region. These experts train our technicians and serve as resources to address the specific needs of our clients.

In addition to pathology and materials expertise, Davey teams develop new technologies to help governments and large commercial properties inventory, analyze, and quantify the environmental services benefits their tree populations provides.
