"We hired Guillermo (G.R. Tree Service) to remove a large diseased Box Elder tree from the backyard of our townhouse. In gathering quotes for the tree removal, not only did Guillermo have the better price, he also had the best plan for how he and his crew were going to remove the tree. We felt very comfortable with his assessment, and he was on-time for both the estimate and the start of the job. He carefully spent the time himself cutting and lowering the branches to not harm any of the foliage around the tree. He communicated nicely with his crew  and together they brought the tree down. Afterwards, he spent a great deal of time and energy grinding out the stump to the fullest extent that the stump grinder would allow, which gives us the ability to plant a tree in the same location all the sooner. Overall I found G.R. Tree service to be a great solution to our tree problem. I would easily recommend them and will be using them in the future, if needed."

"One of the things I love about G.R. Tree Service is that the owner really does love trees.  Others wanted to cut down the majestic cottonwood trees in my yard.  He had a plan for pruning them and giving them new life.  I left for work with trees burdened with too many years of neglect.  I came back to trees that were happy and healthy.  GR Tree Service was so mindful of cleaning everything up, that the only way I knew they were there was by the newly pruned trees.  I also wanted to plant a small tree in another part of my yard.  He knew when to plant the tree and where was the best source for getting it.  He is extremely knowledgeable about trees, landscapes and city regulations.   No one else is allowed to touch my trees."

I own a home in East Denver with many mature trees, and Guillermo has been my arborist for several years. His knowledge of trees runs deep and he brings a kind of intuitive, almost spiritual connection to his work. He seems to love each tree. I am impressed that he can look at a tree and immediately understand what it needs, for its health, beauty, shape and long-term growth pattern.
He does most of his work climbing the trees himself rather than relying only on heavy equipment, which says a lot about both his skill and his respect for the work. Guillermo communicates well with me and his crew. Beyond that, he’s consistently professional, reliable, and fairly priced and leaves the yard looking great. I so much prefer his work to the big tree services which I had used prior to knowing about Guillermo. If you’re looking for an arborist you can trust with your trees, I’d recommend GR tree service without hesitation.
