American Society of Consulting Arborists (ASCA)

American Society of Consulting Arborists (ASCA) The American Society of Consulting Arborists (ASCA) is the industry's premier professional association focusing solely on arboricultural consulting.

Consulting Arborists are authoritative experts on trees. Settle for nothing less than the best when it comes to trees. Consulting Arborists are authoritative experts on trees, consulting property owners, municipalities, attorneys, insurance professionals and others on tree disease, placement, preservation and dispute resolution in addition to providing consulting and expert testimony in the legal, insurance and environmental arenas. The role of the Consulting Arborist is to bring a comprehensive, objective viewpoint to the diagnosis, appraisal and evaluation of arboricultural issues. A higher degree of knowledge and stewardship. ASCA's more than 600 Consulting Arborists separate themselves from other arborists through their commitment to the continual development of their knowledge and skills as industry leaders. In order to maintain membership status and ensure their professional training keeps them current on arboricultural issues, ASCA members must meet strenuous continuing education requirements every two years. To that end, ASCA delivers the best resources for skills development, career enhancement, idea sharing and training in the profession. Our members are held to the highest standards of professional practice. In addition, we are the only source for achieving the industry's coveted Registered Consulting Arborist® (RCA) designation. Our efforts ensure that when an industry professional or property owner hires an ASCA member or RCA to consult on tree preservation, hazardous trees, appraisal, other tree health issues or to serve as an expert witness, they're getting the most authoritative advice the industry has to offer.
