Crown Oaks Arborists was founded in 1994 by Daryl Monson and later incorporated as C. O. Arborists, Inc. in 2008. Daryl’s vision was to build a Professional Tree Care and Landscaping company who provides quality and affordable tree services to the greater Pasadena community.
We remain a family owned and operated company that strives to not only meet, but exceed, our client’s expectations. We are fully licensed and insured for your protection!
Daryl was one of the first 1,000 Arborists to ever be Certified by the I.S.A. (International Society of Arboriculture). There are now over 25,000 Certified Arborists worldwide. He earned his Certification in 1992 by the Western Chapter of the I.S.A. (WE # 0991-A).
Daryl not only has book knowledge of trees and diagnosis, he is a working Arborist. He can analyze tree issues and make recommendations based on over 25 years of experience in the field. His recommendations have consistently helped and successfully maintained the health and vigor of our client’s trees.
Daryl works closely with our crews to ensure the quality, artistic pruning that our company stands for. His philosophy is to never “Top” a tree, rather “Reduce the Crown” in a manner that is healthy for tree and maintains the safety of a tree.
Daryl has worked as a Consultant on several large court cases as an expert witness. He continues Consult locally and would be happy to hear from you!
