Dennis Hanvey knows his stuff. He is certainly someone I would call an expert and safety is first on his list of concerns. He does great work at a more than fair price. Over the past few years he's taken down huge oak and ash trees very close to my house and in danger of doing a lot of damage. He know exactly what he was doing. I've used his services for years, and he's always been a very nice guy to deal with.
