Who turns up
William — ISA Certified Arborist
The arborist who writes the estimate is the one who climbs the tree.
This page is the reason the rest of the site is credible, and it is the one that needs William’s own words rather than a draft.
What belongs here: the ISA certification number, whether he holds TRAQ (Tree Risk Assessment Qualification), the Massachusetts Arborist licence, membership of MAA or TCIA, years in the trade, the firms he worked for before this one, and two or three jobs he is willing to talk about in detail — including one he turned down.
Google has asked for demonstrable first-hand experience on competitive queries since late 2025. A named, credentialed person with a verifiable certificate is the difference between “an experienced team” and evidence.
