"Above and beyond.... VERY PLEASED... Fair price, excellent work, good equipment, prefessional operation.. Was considering doing it myself which would have been a HUGE mistake. Not only did they take down the big tree, they went above and beyond and cleaned up the branches and leaves that had fallen on the patio cover and blocked the skylights. Then on top of that, they made some quick cuts on another tree that was growing wildly near the one taken down. To put the icing on the job, the stump was ground up very well and the ground leveled. ZERO complaints, and to make it easier they were advanced and took Zelle and Venmo. I'm very detail oriented and hard to please butJaime and the crew were frist class."

"They came out the first time to trim my tree. They were professional and on time. They trimmed the tree quickly and left no mess. I decided to take the tree out completely so they quote me a great price. They came back out and remove the tree and stump. Again very friendly and professional and left the job spotless. They always met their times they give and perform a great job.

"Excellent experience with Maya Tree Service, price was very reasonable and the job and clean up was well done. The only reason I rated the customer service a 4 was because for both appointments; estimate and actual work, he was extremely late and did not call to let me know. I would recommend them."
