Diamond Certified

ArborWorks qualified for this prestigious accreditation after passing each step of a twelve step rating process designed by the American Ratings Corporation (ARC).  The ARC surveyed a random sampling of 100 ArborWorks clients, requiring a score of more than 90 on a scale of 100 to qualify as a Diamond Certified company.  Our clients rated ArborWorks not only on the quality of our work, but also on their willingness to return to ArborWorks for further services or refer other consumers to the company.  ARC also verified liability, auto and workers compensation insurance, state license status, compliant status, business practices, financial stability and legal judgement status.  ArborWorks is proud to count themselves among the elite few companies who bear the Diamond Certified award.
