"I needed to have my service drop line de-vined as well as have the offending overgrowth from the other side of the fence tamed and a tree shortened. It was a mess and would have brought down the service drop line come winter. Mr. Jose Gutierrez was extremely professional and considerate when I first contacted him to come by for a quote. I agreed to the quote and date and time to have the work done. He and his co-worker came with proper equipment to do the job and they did the job extremely well and safe! They even cleaned up after themselves. This is the first time I ever had to have work done on the service drop line. It needed to be done badly and I wasn't sure how to go about it, but after some research and comparing GTZ Tree Service with some other businesses that serves the Knoxville area, I felt encouraged to go with GTZ Tree Service. I am very glad that I chose GTZ Tree Service to do the work that I needed done. They were kind, respectful and honest regarding the quote that was given. I do highly recommend them to clear service drop lines or any tree work that needs servicing! Thank you very much, Mr. Gutierrez for helping me and my elderly mother lift a heavy weight that was bearing down on us. Now we don't fear our service drop line breaking in the winter because it's clear and safe! A+ I will certainly use GTZ Tree Service again!"

"These guys are fast, easy to work with, attentive to detail, and make sure you're happy with the job before they leave! They cleared a ginormous pile of tree’s from a past excavation job, and even helped me take out/ move some stumps from mature tree’s that were left on my property! I have a huge area of my yard back, and I couldn't be happier with the work they did for me! I'd highly recommend them for your future needs! Prices are fair, and work is above and beyond! Thank-you GTZ service!"

"Gtz did an excellent job removing four large trees that were close to our house. They responded quickly with an estimate and completed the work promptly. They arrived on time and left the area very clean. Their pricing was competitive and in line with other estimates we received. They went above and beyond to ensure the job was done safely and even helped with a few additional tasks around the yard. I would absolutely recommend them and would not hesitate to hire them again."

"GTZ Tree Service did an outstanding job from start to finish. Their team handled our tree removal, debris cleanup, and brush clearing quickly and professionally.

"It was an absolute pleasure to work with GTZ Tree service. The whole crew were professional and very knowledgeable. Even after dealing with several issues brought on by our neighbors.
