HOW TO USE THE SEARCH OPTIONS: This is a method for verifying someone is an ISA certification holder. Enter ONLY ONE search option at a time for locating Certified Arborists. The search is not case-sensitive. Searching by zip/postal code may result in a broader result than searching by city and/or state. Searching by city and/or state only returns results that exactly match your criteria. Searching by United States zip code will return at least 30 records, looking outside the target zip/postal code you entered if necessary. Searching by a non-United States Postal code will only return records for that exact Postal Code. PLEASE NOTE! 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.
