Hi Geoffrey, I have been meaning to send you this email for some time now, but time just got away from me. Jerry and I want to share with you just how pleased we were with the work your tree crew, John, Juan and Rigo, did for us on July 19th, 2022. They were absolutely awesome. They were professional, courteous, and went above and beyond to make sure that we were totally pleased with the work that they had done for us the day before they left. We also like to thank you Geoffrey for your quick response in getting back to us whenever we call you for service. Your knowledge in caring for trees is evident and you represent your company extremely well and we appreciate you. We have been in our house for over thirty four years and throughout the years we have dealt with many different tree companies. This past spring we started using your company and Bartlett Tree Experts has been the best tree company we have ever dealt with. The tree crew that came out in May when we needed an emergency tree removal were outstanding. We will continue to refer your company to our family and friends. It is so nice, especially these days, to see such great customer service. Kudos to everyone at Bartlett Tree Experts.
Diana and Jerry R., Gambrills, MD

We had a large Red Maple that was encroaching on our and our neighbor’s roof. We needed a lot trimmed back, but wanted to maintain the integrity of the tree.

All Bartlett personnel who came to my home were great. They were pleasant, informative, and patient with me. I was able to watch them work and I am highly pleased with their professionalism as well as their knowledge and experience for tree removal without damage to either my property or my neighbors. Another member of their team came out to spray chemicals on the tree to help keep the harmful insects, to my tree, at bay. I have a Maple and an Oak tree remaining on my property.

He came out several times while the two days of work was being done to ensure it was being done properly, He worked with arborist cutting the tree to ensure that our landscape was not damaged.

Suziann D., Severn, MD

Having an arborist like Geoffrey with whom to work gives me confidence and trust when making decisions that affect the appearance and value of my home. I have also found the price difference between Bartlett and other landscapers to be less than expected. Using Bartlett gives me peace of mind that if problems ever were to occur, I would have a well established and reputable business with whom to deal.
Gloria B., Linthicum, MD

I appreciate all your work. And your honesty when you traced brown leaves to spray being too hot.

Thank you Geoffrey, John, and crewmembers!
Maddie P., Glen Burnie, MD

Carol W., Ferndale, MD

We needed emergency service after a wind gust snapped a tall Virginia pine in our backyard. Called Denise at Bartlett, who was very personable and quick in contacting their arborist, Geoff. He was at the front door in thirty minutes. He evaluated the situation, gave a quote, and the crew was there fifteen minutes later. The team was efficient and well managed, and even blew pine needles off our trampoline during cleanup. They offered a free consultation the next day to evaluate the rest of our trees. I would definitely recommend this company to our friends and neighbors. The best tree service that we have ever had.
Shawn C., Severn, MD

Janis J., Annapolis, MD

The Crew was professional and came together as a team. I was very impressed.
Jan M., Laurel, MD

I am writing to express our gratitude for the outstanding service provided to us by Bartlett on Sunday. Specifically and gratefully, we salute Geoffrey Thill and his team. In addition to removing a large, awkwardly-situated fallen tree from our roof and property, they securely covered the holes in our roof with a tarp and raked the lawn to remove debris. The team arrived on time and worked steadily for six hours. Their work ethic and attention to safety for both persons and property was impressive. So was the collaborative problem solving involved in hoisting the heavy trunk of the tree and its massive branches into position to be cut up and removed. At one point, with masterly precision, they guided the massive trunk into alignment with the gate in our fence. They inspired us, as I am sure they inspire other customers, with their professionalism, skill, and efficiency.
