I worked with Robert from Al Miley & Associates to have a sugar maple in the back of our house looked at to see whether it needed to be removed or it "just" needed a lot of dead wood removed.
Robert was punctual and very reachable over a period of a few weeks as we got a few quotes. In the end, we went with Robert (and Al Miley) because their price was reasonable, and they came across as one of the most genuine/honest of the group that provided quotes.
In the end, we removed a significant amount of deadwood from the sugar maple, and also had some work done to a locust tree.
The Team of 3 arrived on the date promised, at the time promised. They worked through the whole day and did a great job of leaving the sites as clean as possible.
I highly recommend Al Miley & Associates based on my experience.
