OK, let me say right up front that I am not an arborist -- I am in the forestry logging business. So when I need residential tree work done (almost yearly), I hire an arborist. But I have never used a web site (ISA, TCIA, etc.) to find one. I go by personal recommendations, the yellow pages to find one close by, and the professional demeanor of the individual when I get a quote for the job.
Perhaps like much of the general public, certification and accreditation mean nothing to me. Just as when I hire a painter -- I want references from happy customers -- it doesn't matter that he is a member of the International Society of Painters.
What are groups like ISA and TCIA doing to inform the public that certification and accreditation are a good thing? I've been in the tree business for 15 years, but until I joined ArborSite.com, I never new that ISA existed.
In the end, I would be surprised if any such group would be affective at attracting new customers.
