What is an ISA Certified Arborist?

An arborist is a professional who is trained in the art and science of planting, caring for, and maintaining trees and other woody plants. An individual with the Certified Arborist designation has had a minimum of three years of work experience or equivalent in the arboriculture field and has passed the assessment of knowledge hosted by the International Society of Arboriculture (ISA). 

A good arborist will offer a wide range of services such as pruning, removal, disease and insect diagnosis, integrated pest management, etc. There are many experienced tree services that do not employ Certified Arborists but will do a fine job removing a diseased or infested tree.
