Tucson Based

Whitethorn Tree Care is locally owned and operated in Tucson, Arizona by certified arborists with extensive experience in tree care and urban forestry. We combine industry-standard ANSI A300 practices with a deep understanding of the unique challenges facing desert trees and landscapes. We recognize the importance of desert trees, from the ecological benefits they provide to the beauty and value they add to your property. As owner-operators, we are directly involved in every project, allowing us to maintain a high level of quality and attention to detail. Our mission is to protect and preserve Tucson's urban canopy to create a greener, more resilient community.
