About Missouri Arborist Company

Third-Generation.
25+ Years of Credentials.

Missouri Arborist Company is owned and operated by Chris Rippey, a third-generation, ISA Board Certified Master Arborist and ASCA Registered Consulting Arborist based in Sedalia, Missouri. Chris has over 25 years of experience in arboriculture, including 14 years as an arborist at Stanford University and 6 years as Arborist for Seattle Parks.

"As an ISA Board-Certified Master Arborist and Registered Consulting Arborist, the service that I offer you will be appropriate and reasonable. I perform the highest quality of tree work that you will find."

In 2019, Chris was named Arborist of the Year by the Pacific North-West chapter of the International Society of Arboriculture. His practice operates at the forensic and consulting end of arboriculture -- expert witness testimony, sonic tomography imaging, resistance drilling, and tree failure analysis -- services that most arborists do not offer and that require a level of diagnostic precision developed across decades of institutional practice.

Please send a description of your project along with any pictures and I will get back with you to set up a free site visit so I can get you a cost estimate for your project. Contact me with any questions you have. I look forward to working with you.
