Rooted In Expertise Since 1880
John Davey developed the concept of tree surgery, the idea that the health of a tree could be maintained like that of a human being when he founded The Davey Tree Expert Company in 1880. John, known as the “Father of Tree Surgery,” started training the world’s first tree surgeons – predecessors of the modern-day arborist. Today, the employee-owners of Davey Tree are committed to using their knowledge and expertise to deliver unmatched excellence in client experience. And they are dedicated to furthering John Davey’s mission of caring for trees.
Remaining True To Our Roots
The Davey Tree Expert Company has grown from a small seedling of an idea first planted by John Davey into a giant within the green industry.
Since 1880, Davey has set industry standards for tree care and become one of the largest employee-owned companies in North America. As Davey has grown, so too has its commitment to its clients, employees and the environment.
