I have used Oliver Bailey for many years and found him to be fantastic. He cares about trees and is very informative in assessing health concerns. His costs are reasonable and he is very responsive. I had a tree come down on our house during the recent wind storm. I texted him at 12:30 am right after the tree hit the house and he responded immediately and asked if he should come out then! I told him the next morning would be fine. Most of my neighbors also use him now and are very pleased.
