"Tim, is very knowledgeable, hard working and very fair on his pricing. We have used his services twice, once when a 70 year old pine tree blew over and the second was reducing the height of a hedge that had gotten way too tall. I have referred him to several neighbors and friends and everyone has been very pleased with his work."

"Hernandez tree service was phenomenal. They were timely, presentable and overall good to work with. They did a removal of a large dead tree. As well as a trim on a smaller tree. The dead tree removal was in between my house and the neighbor's house and there were zero problems. They worked swiftly and accurately. I would highly recommend for any tree services you may need."

"Sam is wonderful, very knowledgeable and passionate about trees. Sam runs a good small business focused on trees. His team pruned my ash tree, which had a lot of overgrowth, broken branches, dead limbs, etc. Sam focused on multiple issues with trees that the other tree services did not raise. I was very happy with the results."
