Joe and Francina B., Frederick, MD

I have been working with Tim Zastrow and Doug Hartz. I can not say enough about either of them. They are both friendly, knowledgeable, and professional. Once Tim and I assess all our trees and shrubs to determine what treatment is needed, Doug has been the crew member who services our property. I often walk the property with him to get a better understanding of what issues are present. He has been more than willing to answer my questions and allow me to tag along before he starts the actual treatment. Both Tim and Doug are excellent representatives of Bartlett.
Carla H., Frederick, MD

We are very happy with the work that the Bartlett Tree Experts performed on two of our large and older trees. Their initial assessment made us aware of several issues that needed to be addressed and their team of professionals came soon after and conducted very impressive work. We highly recommend Bartlett Tree Experts.
Jim S., Frederick, MD

I could not think of anything. Very pleased with everything. Tim was very nice and answered all my questions. very professional. Thank you.
Kay and Ellis K., Frederick, MD

Everyone was incredibly courteous and knowledgeable about the entire process for both tree removal and trimming. The on site crew was communicative and checked in during and after the job was done to make sure everything was progressing to my liking. Mr. Zastrow was incredibly knowledgeable about the trees and shrubs on my property, and I really appreciated the more conservationist approach to care and maintenance of the trees on my property. I also appreciated the provided recommendations on how frequently I should check some potential future care issues with some of my trees.
Yvonne E., Frederick, MD

Everyone was great.
Matt W., Thurmont, MD

Wonderful.
Lora Wihite, Frederick, MD

Tim is great.
Michelle M., Frederick, MD

As busy as Doug's schedule is, he offers us the opportunity to ask questions to which he gives detailed answers. His knowledge is impressive. Doug always texts the night before, always lets us know when he arrives and allows us to walk the yard with him during his inspections, sharing his findings and possible remedies with us. Could not ask for better service.
Jim and Carol C., Frederick, MD

Everyone at Bartlett was top notch. Very courteous, polite, and left job site neat and cleaned up.

Jim M., Frederick, MD

We may be a contractors nightmare having changed our minds a time or two in the middle of the operation. We have the champion Osage Orange for Frederick County, so you may understand it is huge and a treasure. We love the old tree for many other reasons. When it began dropping limbs we decided to take it down, a process that requires a different approach than preservation. Midway of cutting off the limbs we could not stand killing it so asked instead how we might keep it. That required judicious bracing and limb removal and the radical mental change of intention from the crew. They did a terrific job, the closer trimmed area is sprouting new growth and the tree seems vigorous. But, there was one great long limb over the house that was making me uneasy. They have successfully, really one could call it artfully, trimmed that limb back while preserving a graceful appearance. Their work was outstanding. Safely done with expert guidance from their horticulturist. Many thanks.
Mary C., Jefferson, MD

Very happy with your company and personnel.
Beth S., Frederick, MD

Mickey P., Frederick, MD

Ann M., Frederick, MD

Very pleased with every technician who has provided services. Each has done a very good job in a friendly and engaging manner. Very impressive, knowledgeable, and takes the issues I have seriously. I am very pleased. Overall, Bartlett is the best company I have ever had, taking care of the considerable number of trees on my property. I can not imagine working with another company. Keep up the great work, and thank you for what you do so well.
Joyce J., Woodsboro, MD

It was reassuring to have people I could call profession artists working to preserve our treasured old tree. They trimmed back a massive, heavy limb threatening our vulnerable and brand new metal roof. These young men were clearly well trained putting safety first and demonstrating a thoughtful approach guided by a seasoned, knowledgeable arborist. The tree should look great and thrive for a couple hundred more years. We will let you know.
Mary C., Jefferson, MD

Everyone I spoke with from Tim, to the lady answering the phones, and the young men who came to prune the trees were very courteous and helpful. Any questions I had were answered. All were very professional. It was nice to have the pruning done in such a timely manner.
Kathy K., Frederick, MD

What could Bartlett have done to make the experience better? All good. They were responsive and skilled. I appreciated Tim's explanations and information about the condition of our Dogwood and shrubs.
Susan K., Frederick, MD

Tim was very knowledgeable in helping us to make our decision on treatment vs not. Thank you Tim.
John M., Frederick, MD

We have two very large 100-year old sycamore trees behind our house, both with deadwood which had started to break off and fall on our patio area. We were concerned that this was a dangerous situation, so we contacted several tree companies in the area to get estimates. Tim Zastrow, the arborist sent by Bartlett Tree Experts, did a really nice job explaining to us the type of maintenance sycamores need, we were confident that the solution he proposed was the right one. He also recommended putting in a lightning protection system in both sycamores, which we thought was a pretty good idea. Bartlett's wasn't the least expensive of the companies we contacted, but it also wasn't the most expensive (by far). Tim offered a discount if we wanted to wait until November to get the work done, but since the deadwood was falling now, we decided to go ahead and schedule the work. The team that came out was excellent -- they arrived exactly when they said they would and did exactly what we contracted them to do. The tree climbers are highly skilled. We were worried that falling branches might hit our new metal roof, but the climbers were careful. They did a great job, and our new lightning protection system will be a conversation piece for sure. The job took most of the day, and Tim came out to check on the work himself. It was an all-around nice experience. We have a dying pine tree that needs to be removed and we will schedule this work with Bartlett's in November to get their winter discount. We are really happy with the work they did for us, and we will be repeat customers for sure.
Shawn T., Chevy Chase, MD

Tim is, of course the tree guru of Montgomery County, and he was exceptionally helpful as we decided the future of a sycamore on our property -- actually two sycamores. He was also patient as he taught me about how a tree feeds sustains itself and grows -- and where to look for the weak spots and the signs of decay/trouble. We decided to have one large sycamore trimmed and re-cabled. His crew was prompt, professional, skilled, and considerate of us and the neighbors. They left the work site spotless, and left everyone involved happy.
Debra R., Bethesda, MD

I cannot pay enough in praise of their professionalism and personal efforts. Their relationship with each other was seamless. Each knew what he had to do, alone or with the others, without "to do", did it. What's more after all of the cutting, sawing, chipping, stacking, etc., they cleaned up my garden, front and back, and finished by sweeping the area in front of the house…I'm still impressed.
June S., Chevy Chase, MD

Arborist is exceptional (Tim Zastrow)- high competent, and truly interested in his work. Crew members are incredible - they sure know what they are doing.
