At Tree Theory we are dedicated to providing great customer service with honor and integrity. We always incorporate the latest standards and practices in the industry and stay until the job is done right.   

Tree Theory started out with two guys and their love for trees. We have since blossomed into a full-service tree care and consulting company. We offer a variety of services to help our customers maintain beautiful, healthy trees and shrubs. Our primary goal is to diagnose and treat your tree health issues. We consult with private homeowners as well as landscape professionals, HOA’s, and property managers throughout Arizona. 

Since most Arizona communities are man-made engineered landscapes it is important to understand that if not properly maintained they will turn back to dust and sand rather quickly. For this reason, we expanded our team of experts to help you make the best choices.
     

Our team

• We have one of the leading arborists in Phoenix. He and his team will assess the condition of your tree, shrub and all landscape components and make a diagnosis along with recommended treatments. 
• We work with multiple irrigation experts that will assess all irrigation and bring issues or recommendations to your attention along with the most cost-effective solutions. 
• We work with multiple landscape architects that can accommodate any design or re-design. 
• Last but not least our fertilization/Soil Amendments team will assess the nutrients in the soil and your trees water uptake and determine if treatment is needed (always strategizing with the other experts on the team).
