TCIA Accreditation


Tree Care Industry Association (TCIA)

Think of the Better Business Bureau – for tree companies. TCIA is an international trade association dedicated to the development of expertise, safety, and protocol in the tree care industry. TCIA members who are not accredited receive access to educational resources, but are not required to implement the recommended procedures and standards.

What is TCIA Accreditation?

In order to become TCIA Accredited, a company must pass over 80 points of inspection that prove it has implemented top-notch procedures across the board. Accreditation requires that staff remain up-to-date in the latest technique and safety advancements, and adhere to the highest industry standards in every area of operation. Of the approximately 20,000 tree service companies in the United States, only 200 hold accreditation status. That's 1%. When you hire a TCIA Accredited company, you can have confidence that the team has Certified Arborists on staff, is properly insured, and has earned their place in the top 1%.
