Welcome to Arbor Doctor LLC! 

Our team will provide you with landscape and tree care solutions in Greater Cincinnati, Southwest Ohio, Northern Kentucky, and Southeast Indiana.

Unlike pesticide-centric plant health care programs, our organic nutrients are healthy for your plants. The nutrients thicken the cell walls to help the plants defend against insect attacks and be as resistant as possible to disease. Pesticides may still be utilized, but only in a targeted, limited fashion. We use pesticides which are low or no toxicity whenever possible.

Judy, Landen, Ohio area.

A rep stopped by and eliminated my concerns. Thank you so much for taking care of this so rapidly. I hear you are all very busy. See you later this spring.

Jeff, Mason

Ron, my deepest thanks for making time in your busy schedule to transplant the tree my mother gave me many years ago. I recommend your company to all my friends and family. You are truly an honest caring individual with deepest passion for your work. I also want to give a shout out to (Certified) Tree Service for recommending you. I have taken your advice and created a mulch bed of pine bark for the tree. It has taken wonderfully to it’s new location. Thank you and may you have a blessed summer.

Marcos, Liberty Twp.
