We used American Tree Masters to do quite a bit of tree work around our property recently, and had multiple trees in the backyard that needed very heavy trimming (they were very large Mesquite trees, and hadn't been trimmed in several years, and they were drooping down and almost touching the ground), and a very large tree in the front yard that we wanted removed (my husband said it was too close to our house and roof, and was worried about the tree causing damage to our house). One of our neighbors had recommended American Tree Masters, and said that there crew did a wonderful job on their tree project, and that they had used their company several times over the past 5 years. We called their office to schedule a time for a free estimate, and we met with Dan the owner of the company, and he prepared a written proposal, and explained everything very clearly of how the project would be performed and what to expect (I was very impressed that the actual owner of the company was the person I met with for the estimate, I figured they would send out a salesman on commission just looking to make a sale, but meeting with the actual owner of the company impressed the heck out of us!) When the day came for our project to be performed, we were very impressed to see that the crew not only showed up on time, but took great care to protect all of the small items in our yard, and also were diligent enough to put tarps over lawn ornaments to protect them from any wood chips or sawdust. The crew leader began the project by explaining to us exactly what was going to happen from start to finish, and he even explained exactly how his arborist was going to approach each tree, because he explained to us that the pruning for each different tree type is approched differntly, which I was impressed to learn about. We are so pleased with the results, their crew worked very hard in the heat and did a great job on our trees. We already gave them a great review with the Better Business Bueau and Angie's List. Definitly recommend American Tree Masters!
