Try calling him again, and again. Remind him that word of mouth advertisisng can be good or bad. If he charged you $500 to prune 2 trees he can take a minute to talk to you about them. You may be able to buy an hour of his time to write out a report on the tree's condition.He has not returned my call. Kinda fishy I think.
If he's experienced, his opinion counts. The only thing ASCA membership shows is some education and experience, and the willingness to invest $365/year just to have that membership. They do not provide haloes in the membership packet.:monkey:
