Got quotes from 3 companies on Thumbtack. These guys were the most professional and responsive in getting a site visit, providing insurance verification. While on site they were very impressive, provided a great price and said it would take 20 minutes to remove a 20 ft mulberry tree. They did it while I waited, complete with a very good clean up. Also put a stump killer on it so we should not have to do this again. I have used a couple of other arborist before that did very good work, too, but at a much higher price. Also, they are very safety conscious, wearing hard hats and safety shoes. Could not have asked for a better job. Will use them again.
