Verify a Credential
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 Credential tool allows
homeowners and business owners to locate an ISA certified professional or to verify the credentials of an individual
claiming to be an ISA certified professional.
Using This Tool to Verify/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 firstname.lastname@example.org.
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.
Use the Verify an ISA Credential search tool to verify
credentials and find a certified professional in your area.
