Why Ohio homeowners should know it
An ISA Certified Arborist has passed an exam covering tree biology, pruning, diagnosis, and safe work practices, and is required to keep up with continuing education to keep the credential. It is the most common professional credential ProFix surfaces for tree-care work.
Ohio does not state-license tree services, so credentials like ISA Certified Arborist carry more weight than they would in a license-heavy trade. Pair the credential with workers' comp, general liability, and proof of recent local work before approving climbing or removal jobs.
