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 that made the entire process feel comfortable and collaborative.
They 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.
What distinguished their service was a comprehensive approach to restoration. Rather than focusing solely on immediate concerns, they developed a tailored plan to support both current recovery and long-term plant health. Their recommendations were practical, well- informed, and clearly grounded in extensive professional experience.
Overall, this arborist combines deep expertise with a personal, kind, and supportive touch. We highly recommend their services to anyone looking for knowledgeable, trustworthy, and compassionate tree and plant care!

“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.”
