About Arbor Doctor LLC

arbor-logo-4Arbor Doctor LLC is a full-service tree and shrub care company. We specialize in the care, treatment, preservation, and installation of woody landscape plants using the most innovative methodologies and up to date information. We are different from most other companies in that we are a business which passionately strives to be on the cutting edge of constantly evolving research and technology. It is not acceptable to come out and spray shrubs on a calendar basis. Today’s Plant Health Care practitioner must combine a knowledge of the entire ecosystem and the interactions therein in order to provide a service which is both valuable and environmentally sensitive.
