Ron was a real pleasure to work with from beginning to end. He is very knowledgeable and made great suggestions for my trees. Not one time did I think he was trying to take advantage like some companies try and do.

Chuck H., Wilmington 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

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

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.

Liam C., Claymont, DE
