The term "tree service" applies to any company specializing in tree removal, trimming, or doctoring. Only seek advice from individuals who are qualified to give sound advice, such as certified arborists.

When the price seems too good to be true, it usually is too good to be true. The Best Pick Reports research identified a number of very good tree services.
