Gabi and his team are exceptionally talented. We had a substantial eucalyptus tree situated in the corner of our yard, alongside a pond. Remarkably, Gabi and his team successfully felled the tree without causing any harm to the pond or surrounding landscape. Their communication among themselves was truly impressive, and witnessing their seamless collaboration was truly awe-inspiring. While cutting the tree, Gabi made an unexpected discovery - a hummingbird's nest with eggs. He quickly requested one of his team members to send up an empty bag, and with utmost care, he safely placed the branch containing the nest inside it. Once they completed their work, Gabi thoughtfully relocated the branch with the nest to another tree in my yard. This kind gesture was truly heartwarming. It is worth mentioning that Gabi and his crew displayed utmost professionalism and left my yard immaculate, as if they had never been there. Without hesitation, I would highly recommend the services of this Certified Arborist to anyone seeking a professional, wildlife-conscious, and skilled crew. read more

We had the pleasure of working with an incredible team of professionals for tree pruning, risk assessment, and disease diagnosis. They share our values of preserving trees and maintaining the natural beauty of the landscape. We are thrilled to have found such a knowledgeable group. Their expertise in trimming trees promotes healthier, fuller growth, and their ability to diagnose and treat diseased trees minimizes the need for full removal. In a desert landscape, their understanding of native plants and how to care for them is essential for both the environment and our personal well-being. We highly recommend this company for their exceptional skill and dedication to their craft. read more

Gabi did a wonderful job trimming and pruning our front yard tree. It had never been pruned professionally since we planted it many years ago so was in great need to get under control and formed well. I did not want the seemingly typical "mushroom" cut - cut all the lower branches and leave the mushroom cap on top. I wanted it to look more natural; as the tree would be in nature. He came out promptly, scheduled me a couple days later and took care of it within an hour. Looks great! I told him that it feels like it didn't even get trimmed though his trailer was full of trimmed branches. Will definitely have him back in a couple years for another updated trim. read more

Gabi and Fernando did an incredible job for us! We had very tall, unsightly cypress trees that detracted from our patio area. Fortunately, this local team happened to be doing storm damage on a tree next door, so we were able to get a quote on the spot for the removal of our four trees. Gabi worked us into his upcoming schedule. The team arrived right on time for set up and did a thorough job of taking the tree down, processing the refuse, hauling everything away, and beautifully cleaning up afterwards. They were polite, knowledgeable, friendly, efficient and hard-working. I would heartily recommend The Certified Arborist to anyone. -Jim Franks, Tucson read more

I was horrified to discover that my Texas Honey Mesquite developed blackened limbs, open wounds and cracked bark, seemingly overnight. I contacted Gabi, who visited the next day. He diagnosed my tree as having a fungal infection. Gabi assured me that a native tree has what they need to fight a fungus and recommended adding a microbial inoculant to the soil in early spring to help fortify my tree against the fungus. It was a great relief to me to be given a solution that didn't involve poisonous chemicals. I was very pleased with Gabi's visit and will call on him again whenever needed (plus, my shy dog really liked him). read more

I love Mulga trees (Acacia aneura). Although they're not native, they are perfectly suited to the our desert climate. I planted three of them in my courtyard nearly 10 years ago and they have grown and spread to over 15 feet! The HOA was getting on my case sayting that they "obscured the contour of the roofline" and that something had to be done. I called Gabi and he and his crew came to the rescue. He determined that the trees didn't need to be topped so much as thinned down. Despite getting some hassle from the HOA, they prevailed and did an excellent job. This is the second time Gabi has come through for me. read more

I don't usually give reviews. This is my first on Yelp. But I want to give a big shout-out to Gabi and Dylan for their excellent work. When it comes to pruning trees, Gabi is an artist. He skillfully climbed up my old mesquites. Then like a potter trimming clay, he cut the suckers and old growth and brought forth pleasant and sturdy canopies waiting. I can't wait til spring to see how they thrive. I planted these trees 40 years ago They're like my kids. He treated them with love and care. He's skilled, trustworthy, a good communicator, and very professional. I can't recommend him and his team enough. read more

Gabi and his crew completed work for us yesterday on two large trees; a mesquite which had significant storm damage and an older palo verde that was losing limbs and appeared to be failing. He assessed the trees health and did strategic, thoughtful work to save both. He is both methodical and careful and took every safety precaution for himself and his crew but also for our yard during the work process. Our trees are once again balanced and a beautiful part of our yard. He is truly a certified arborist. read more

Gabi Tadeo with The Certified Arborist is very knowledgeable, personable and trustworthy. He and his crew are dedicated to saving our very large Eucalyptus tree in our front yard.

His price was very reasonable and they did an excellent job from start to finish. We would highly recommend this company for your tree needs. read more

Our experience with the Certified Arborist, Gabriel Tadeo and his helper, Dylan, was great. They were timely, efficient, and did a great job. They got the dead wood out of three quite large mesquite trees and shaped them to promote healthy growth in the future. Gabriel was thoughtful about his work and knowledgable. Both were considerate to us and neighbors, careful and did a great clean-up when they were done. They were a good team and we highly recommend The Certified Arborist. read more

Gabriel came out to assess the huge leaning palo verde in my yard. He found a creative solution in bringing over a few small boulders to buttress the tree at its base. His team also gave the tree a good haircut to lift the deadweight off it. Gabriel is professional, knowledgeable, and 100% reliable. He even worked with me on a payment plan without making a fuss. Thank you Gabriel & team! I will call you again when needed. read more

i consulted Gabby on the recommendation of our general contractor. I asked for consultation at both our home and business. i cannot rave enough about his service at both places. He is obviously knowledgeable and provided me with advice on what I can do myself and what might require more expertise from either him or other service. I felt immediately that I could trust him. I will be calling on his services frequently read more
