Directory of Certified Arborists for Hire

There are over 12,000 ISA Certified Arborists in the US and Canada. This directory was produced so that people in the area served by Wisconsin Arborist Association can more easily locate a qualified arborist.

ISA arborist certification is a voluntary program providing recognition of one's professional knowledge by one's peers. Recognition is given by the ISA to those who: 1) meet the eligibility requirement for admission to the examination, (2) successfully complete the examination, and (3) maintain the necessary Continuing Education Units (CEU's) for recertification every 3 years.
