What our Customers Say About Us.

I have known James Riboli and Arborist, Inc for the 33 years I have lived in Marin. James and his crews have cared for my trees for that time span, and I can’t imagine anyone else doing what all they have done - including assembling a crew on a Saturday night for emergency work the next day. They are honest, they take care of the property, and know and understand trees. I cannot either thank or recommend them highly enough.

Helen Hamilton – Home Owner

I do not hesitate to recommend Arborist Inc for a tree company. James Riboli is a certified Master Arborist, and I have used him on two occasions for reports needed for the county. He is knowledgeable in tree disease, and lets me know when I need to have trees sprayed for pests or fertilized. He has also done an excellent job of pruning my trees and has even done a needed tree removal. Please call him for your tree work! You wont regret it

Christine Wood – Home Owner, Tiburon, Ca

Arborist Inc has been my “tree guy” for the last ten years. The owner James Riboli is honest and dependable and lets me know cost up front. I highly recommend him for all tree care needs.

Isaac Patry – Home Owner, Vallejo, Ca

I have 3 live oaks in my yard that over the years had grown to the point that they were blocking sun to my vegetable garden. Jim and his crew came and cut the sides back allowing an additional two hours of sun to the garden. That is no big deal but to do it so that the trees don’t look like they have been pruned is an art that only a dedicated arborist can accomplish. Pleasing to the eye while taking care to not over prune the trees. Definitely recommend Arborist Inc.
