I had moved into a home that had an enormous maple tree that was very close to the house. Dave advised me on the tree because I did not want to remove it at that time. His company cut back the crown significantly so that it did not impede wiring. He also cabled the tree so that it would not split (it was three tree trunks growing out of a single trunk). He improved the safety as well as the health and beauty of the tree. He is an expert arborist and was also exceptionally nice and professional to deal with. His team did an enormous amount of pruning and work on the tree and the area was spotless when they left. I understand that they do all manner of tree work and are also able to uproot and relocate fully grown trees with large machinery that they invented or adapted. My work was quite involved but they made it look easy. Cannot recommend them highly enough.
