"Edgar with Ziggy’s Tree Service was communicative and professional. While he was out here for a stump grinding, I asked him to take a look at one of my adult trees that had a dead branch. Instead of trying to sell me on more services, as I’ve had in the past, he told me to keep an eye on it and give it another season, and to call him again next year if the branch was still dead. He was also quick and efficient with the stump grinding, and thoughtfully refilled the hole left behind when he was done!"

"Demir came out and took down the Aspen tree that was fallen and unsafe and hanging on another tree branch on a Sunday, then came back with the crew the next morning. They did a great job and the aspens look really healthy now and safe for the next windy day in Colorado. They even raked up and cleaned the backyard. I would definitely hire Hernandez Tree service again - excellent job and reasonably priced !"

"Sam and Jake removed many aspen trees from my property and trimmed several other trees. They did exactly what they said they would do and they charged per their quote without any overruns.
