I have been a faithful customer of Bartlett Tree Experts for many years. On July 6, 2021 I met with Ron Kowalski, Arborist Representative at Bartlett Tree Experts to receive an estimate for work to be done on our property. As usual, Ron has all the answers to my questions and was able to have a huge job begun and completed within days.Todd Kilgoe and his partner, Scott McDaniel are exceptional in every way their job required them to be. They each were courteous, knowledgeable, and respectful with a great sense of humor. A customer could not expect any more.Todd, Scott, and Ron are the reason why I will always be a returning customer. Because of Todd and Scott’s magnificent work, I will happily give my development’s President Todd, Scott, and Ron’s names so that he can pass said information on to other Cooper’s Run Development home owners. Lastly, Todd Kilgoe and Scott McDaniel, I wish you both the very best always and I hope Bartlett realizes what a treasure they have in employing you both as part of their business. It is because of their attention to detail with their other special qualities that I have already stated that I will continue returning time after time after time.

Ron Kowalski was extremely knowledgeable about the infestation of my Holly tree. He explained everything clearly to me and showed me the insects with his magnifier. He explained the treatments that would be necessary to stop the infestation. He returned when I became very concerned about the tree losing so many of its leaves. He has given the tree one treatment and I am already seeing an improvement. He will treat the tree again in August. He is definitely an expert in his field and also a very nice person. I am happy that I chose Bartlett to handle my problem and save my tree.
Helen J., Middletown, DE

Great service and expert advice.
Linda M., Bear, DE

Linda M., Newark, DE

Ronnie, I want to complement the crew that came out and worked on our property on the morning of Jan 7, 2021. The job looks great and all members of the crew were very professional. The person who worked in the trees really knew his stuff and was impressive working his way from one tree to the other as he cut it down to size. The Holly on the side of the house looks well trimmed. Once again, thanks for a good job. Left property well cleaned up.

Janis C., Dover, DE

The three guys who worked on my trees did a most wonderful and professional job. Large limbs were tied-off and lowered to the guy on the ground and smaller twigs were carefully dropped away from the plantings below. No plantings were injured. This was a problem with a previous tree company who we no longer use. Ronnie got the guys started off indicating where the work was to be done and he tied a blue ribbon around the trees requiring work. The guys were very pleasant and easy to talk with. The clean up was terrific, no trash was left behind. I will use Bartlett again and will recommend them to family members and neighbors.
Ron H., Elkton, MD

Used Bartlett for eighty Blue Spruce trees on our HOA common ground. Ronnie was professional from start to finish. Had contact with another crew member that sprayed a half dozen trees on my personal property and he could not have been nicer. Had some bunnies in the yard and a nesting bird I was worried about. He managed to spray the trees without getting spray where it would harm the animals. He waited while I covered areas with tarps to keep spray from the grass where bunnies may eat.
Eleanor N., Camden, DE

Ronnie is a great guy to work with. Tree Trimming work was exceptionally good.
Gerald L., Smyrna, DE

You guys did a terrific job today. The lead guy who did all the talking is exceptional in customer care. He deserves a raise.
Brian M., Wilmington, DE

They did an amazing job of taming our never pruned magnolia. When I stopped by to see the progress they stopped what they were doing and spoke to me in layman’s terms everything they were doing. I appreciated the special attention. Thank you Bartlett!
Anneke S., Dover, DE

Logan and Ben were such a delight to have on our property. Mike, who does our spraying is an absolute delight as well. There is no slacking or cutting corners with the employees of Bartlett. I understand why the price of work is what it is, as you get what you pay for and more. I certainly cannot say enough about the company, and the quality of work that all of you execute for your customers. The performance of each and every one of you is held to very high standards, simply exceptional, and above the norm. Our trees are doing so much better since Bartlett started to work with them, I am so pleased. These trees are our family and I cannot thank you enough for nursing them back to health. We are so grateful that you came into our family. God Bless and have a great day.
Sally G., North East, MD

Everyone from my initial inquiry were highly professional and accommodating.
Janice M., Dover, DE

Ron was great to work with, he gave me a great plan to save my Norway Maple. Gus was polite and efficient.
Liam C., Claymont, DE

Great experience with everyone. Already planning our new list we would like for them to do.
Jerry B., Townsend, DE

Our development has between 75 and 80 giant Blue Spruce Trees that have the beginnings of bag worms. We contacted several tree service companies and spoke with arborists from the companies. We found Bartlett's, Ronnie Kowalski, to be the most straight forward and knowledgeable. Ronnie explained the various issues our trees were having and the appropriate course of action. Your prices were in line with other companies, but we felt the products and course of action provided by Ronnie on behalf of Bartlett was the best plan. Basically it came down to feeling the most comfortable with Bartlett. We have recently had the trees fertilized and will have bag worm treatment later in the summer.
Eleanor N., Dover, DE

Ron Kowalski is a great representative for the Bartlett company. Crew members Gus, Victor, Jesus, and Jeramy were very professional. I am very happy and satisfied with the level of service I received.
Wyatt W., Dover, DE

The crew that installed our trees were very courteous and helpful.
David L., North East, MD

Starting with Ron Kowalski, I have never met a person more willing to please and take time to provide background information on work to be done as well as excellent details regarding trees and shrubs already on my property. I am a tree lover, so we had a lot in common in that regard. The crew was very pleasant and hardworking. I could not be more pleased with Bartlett Tree overall. Thank you.
