Client Experiences
What Clients Are Saying
William Mellott is the real deal. When our property suffered serious damage from a water rights dispute, he came out personally, assessed every tree, and produced a thorough arboricultural report that gave us a clear understanding of the full extent of our damages. Beyond his impressive credentials, what sets William apart is that he genuinely cares. He treated our land like it was his own. I cannot recommend him highly enough.
Stephen Craun
Property Owner, Athol, Idaho
We couldn't be happier with the arborist services we received. From the very beginning, the years of knowledge and experience were evident, along with a personal, kind, and supportive approach. Will and his team completed a thorough and thoughtful assessment of the damage to the plants and trees in our yard, taking the time to clearly explain what was happening and why. We never felt rushed, and all of our questions were met with patience and genuine care. We highly recommend their services!

Property Owner, Spokane, WA
After having had our home appraised last year I wanted to know the value of mature shrubs and trees. I turned to New Leaf Nursery for help. They quickly recommended Will Mellott as the guy I needed to talk to. Will responded quickly and surveyed my property the next week and provided me with a detailed report. Excellent work.
