We have a very large big leaf maple right next to our house so we needed to make sure it is still safe. Vitalitree culled a lot of weight off the top and cabled the 3 sections of the tree together to make it safer (it is split at the bottom and makes 3 trunk sections). They also inspected and culled our large western red cedar tree. The crew are all employees of Vitalitree (so not contracted workers). I don't know anything about trees, but it appears they did an excellent job. Good clean up as well. They also were attentive to our requests. I would hire them again.
