What is a Certified Arborist?


An arborist by definition is an individual who is trained in the art and science of planting, caring for, and maintaining individual trees. ISA Arborist Certification is a non-governmental, voluntary process by which individuals can document their base of knowledge. It operates without mandate of law and is an internal, self-regulating device administered by the International Society of Arboriculture. Certification provides a measurable assessment of an individual's knowledge and competence required to provide proper tree care.

Certification is not a measure of standards of practice. Certification can attest to the tree knowledge of an individual but cannot guarantee or ensure quality performance. Certified arborists, like Turning Leaf Tree Service, are individuals who have achieved a level of knowledge in the art and science of tree care through experience passing a comprehensive examination developed by some of the nation's leading experts on tree care.

Certified arborists must also continue their education to maintain their certification. Therefore, they should be up-to-date on the latest techniques in arboriculture.
