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.
