I will continue to recommend Bartlett to anyone I feel could use their services. A professional organisation.
Pat F., Grapevine, TX

Gareth sent above and beyond what would be expected. He contacted Rachel Richter,an Urban Biologist with Texas Parks and Wildlife, several times to thoroughly understand egrets and their lifestyle in order to correctly fix my trees. The trim on my trees is proof of His knowledge. Thanks Gareth.

Erin W., Fort Worth, TX

Gareth and Clint are just amazing. And what great customer service it is that two years later I have the same contacts and crew members at my property. Can not thank you enough.
Kristin J., Azle, TX

I am delighted with the results after having my trees trimmed and overgrown bushes taken away. The crew worked so hard on a very hot day and got everything done and cleaned up in time for the movers to unload my belongings. Very nice guys, they were polite and respectful of the neighbors yards and driveways. Will definitely use your company again.
Anthea M., Benbrook, TX

Staff were knowledgeable and professional. Gareth Harrier earned my trust with his knowledge and honest assessment of my problem, possible actions and potential outcomes. The trimming crew was professional and did a good job of handling some potentially hazardous situations. The clean-up of small twigs and branches could have been more complete. It took me an hour or so to finish the clean up.
Randal M., Fort Worth, TX

Gareth was friendly and helpful in areas of concern. The staff was efficient and courteous and the work was done in a timely manor and the area cleaned up afterwards. I have a high regard for your company and would recommend it to any of my friends who were in need of your services. Thank you for all your work.
Betta B., Fort Worth, TX

Gareth was outstanding, professional, thorough, and courteous. Much appreciated.
Russ R., Arlington, TX

Gareth was very responsive and I sincerely appreciated that he steered me away from expensive tests that would not be useful in evaluating my tree's condition. I was out of town when he first came over to look at my tree and he took a professional and consultative approach over the phone. I think it was James whom came over to treat the tree and he was also very knowledgeable, friendly, and reassuring. I will recommend your company to friends in the future, just as Travis Kennedy did to me. Fingers crossed for the tree to survive, but I am confident that you all are doing everything you can to help me save it. Thank you.
Trey S., Fort Worth, TX
