I highly recommend this business. James came out quickly and gave us expert advice about our fruit trees. One of our Pear trees was clearly diseased and he was able to quickly diagnose the problem. He explained things slowly and effectively and was super responsive to all questions. We have about twelve fruit trees in our backyard and he walked around and examined each one, giving advice and support. We can not wait to use his service again and will be scheduling yearly appointments for his team to help us with pest control. If you have trees that need help, do not wait, this is a great business.

Arborist James has been outstanding in providing us with the info and understanding about our trees and steps to keeping them healthy. Thanks for your good customer service.
Gary G., Castro Valley, CA

From the first consultation to the last service, Mr. Riddle has been courteous, friendly, and very knowledgeable. We will definitely reach out for future service needs. The crew members were methodical and careful not to damage other things in our backyard. They took extra time to ensure that there were no debris left. When they were done, they did not just drive away but rather spent a few more minutes explaining what they had accomplished. What great service. Thank you Mr. Riddle and his very professional and friendly crew for their help with our service needs. We will definitely be reaching out for future needs and refer our friends and family. Stay safe and healthy.

Bartlett was the last of the four companies we had out for an estimate and James Riddle was who came out from your company. We wanted an estimate for pruning our nine Queen Palms and having another removed. After meeting with the other companies my husband had made a comment to me about buying a laser pointer so that I could use it next time to point at which fronds I wanted removed and trimmed. If they had one to use, It would have taken less time out in the sun with them. Not only was James pleasant and informative, he knew how we wanted the fronds trimmed and which ones removed because the first thing he did was pull out his laser pointer. Most importantly, I wanted a lift used to trim the fronds instead of using spikes to climb the palms. The crew members Ryan and Alberto were very cordial and communicated with us to insure that the job was being done as we wished. I requested that James come out to oversee the job and he did at the beginning as he said he would. We are absolutely pleased with the job and highly recommend them.
Susan, H., Pleasanton, CA

James Riddle was exceptionally knowledgeable and helpful in his proposal; and the tree they "cleaned up' looks great. It makes the whole South side of the house look more attractive. I've already passed your name off to my brother and sister-in-law.
Ray B., Pacheco, CA
