ISA Certified Arborists

Credentials, not claims

What an ISA-Certified Arborist is

An arborist is a professional trained in the care of trees. A certified arborist has gone a step further and proven that knowledge through the International Society of Arboriculture — the leading credentialing body in the field.

Earning the credential is not a matter of signing up. Candidates need a minimum of three years of full-time, practical arboriculture experience (or a qualifying degree combined with experience) before they can even sit for the 200-question exam covering ten areas of tree care — from tree biology and diagnosis to pruning, safety, and risk assessment. Certification must be renewed every three years through ongoing continuing education.

Why it matters

Why hiring a certified arborist matters

The difference between a certified arborist and someone who simply owns a chainsaw is the difference between informed care and guesswork. That gap has real consequences for your trees and your property. Hiring certified tree services is how you make sure the expertise matches the stakes — especially on large or high-risk jobs.
Certified Arborist 1

Correct Diagnosis

A struggling tree can have many underlying causes — disease, pests, root damage. A certified arborist can tell the difference and recommend the right response, rather than removing a tree that could have been saved or treating a symptom while missing the cause.

Certified Arborist 2

Proper Pruning

Bad cuts do lasting damage. Trained arborists prune in ways that support a tree's structure and health, avoiding the topping and over-cutting that leave a tree weaker and more prone to failure.

Safer Work

Tree work is hazardous, and knowledge is a safety tool. A certified professional understands how a tree will respond to each cut and how to bring it down or thin it out without endangering people or property.
