Verify a Certification

Becoming an ISA credential holder requires a commitment to understanding current safety standards, best practices in arboriculture management and the importance of working with the public in a manner that is professional and informative.

We encourage the public to hire a certified professional when the time comes to care for the trees on their property. The Verify an ISA Certification tool allows homeowners and business owners to locate an ISA certified professional or to verify the certification of an individual claiming to be an ISA certified professional.

Using This Tool to Find a Certified Arborist

Anyone who shows up in the search results using the tool below are currently certified by ISA. Please note that credential holders have the option of not listing themselves in our public database, but they may still be ISA certified. You may also verify a certification by contacting the Certification Department at cert@isa-arbor.com.

If the person you are searching for has moved and has not notified ISA or updated the information in our search database, you may not get search results but they may still be ISA Certified.
