Hey Michael, don’t know if you remember us, but relative to the avocado tree in our backyard in Long Beach, we took your advice. The tree is coming back with bright green new leaves and it seems to be doing 100% better than it was!

Simply put, Ruben Green is a consummate professional.  As our Consulting Arborist, he has been smart, thoughtful, reliable, and a pleasure to work with in every respect. He’s earned not only my trust and appreciation, but also my highest recommendation.

We won!

I have used Evergreen Arborist on many occasions and he is one of the best arborists in Los Angeles when it comes to trees. He is very knowledgeable and provides quality reports. I refer him to many of our tree pruning clients. Thanks Ruben for all the great work and for all your help.

Mr. Green and his team are extremely professional and knowledgeable. He is one of only a handful of Consulting Arborists in the country that is willing to take on tough cases relating to tree liabilities. His industry experience shows in the quality of his work. I highly recommend Evergreen Consulting Arborists!

This may be the most enthusiastic review about an arborist that you’ll ever read. I realize that most people won’t ever need an arborist, but if you do, there’s only one person to call. Mr. Green entered my life in a moment of crisis. After a “streamlined” review process (two months), the City Planning Department was about to sign-off on my home renovation permit. The final sign-off was due on this particular Wednesday and I was excited to head down to the planning department to pick up the final permit.

This plan went out the window when at the last minute I received word that the City’s Urban Forestry office was concerned about an oak tree in my yard and would require an arborist report and recommendations to protect the tree. I frantically searched arborists in the area. I hurriedly explained my situation and Ruben assured me that this was well within his area of expertise. He is very familiar with the report that the City’s Urban Forestry department requirements. It was my lucky day (despite the permit not being ready)!

Ruben quoted me a fixed price for the report and offered to come out and look at my tree within the next two days. In the meantime, he asked me to send along pictures and site plans so that he could being preparing the required report for the City. Ruben arrived to my house on Friday and turned in his final report to the City within a few days. Mr. Green understood the urgency of my situation and actually cared quite a bit that his arborist report and recommendations would be received and approved by the City. Guess what? It was approved by the City and my permit was issued two weeks later (which is “immediately” in Palo Alto Planning Department time).

Ruben Green has a great understanding of the “process” and truly cares about the clients he works with. He knew that I was in a panic when I called him yet he quoted me a very fair and reasonable price and did an absolutely fantastic job. He is highly responsive and should be your “go-to” arborist if you find yourself in a similar situation. Thanks again, Mr. Green!
