Certified Arborists List - Consulting Arborists
 This
list of Certified Arborists for hire is provided as a public service by the International Society of Arboriculture, Pacific Northwest Chapter
(PNW-ISA), a professional association of arborists in Idaho, Oregon,
Washington, and British Columbia.
Look for this logo when you hire a tree service company - it is a sign that an employee has passed the ISA Certification Exam. To use the term "Certified Arborist", an individual must have three years of experience and have passed a certification exam that tests a variety of tree care knowledge. Not all arborists are qualified to provide all arboricultural services, and Certification is no guarantee of performance. As with any service you purchase, it is best to shop around, ask for recommendations, and get written estimates. Most Consulting Arborists provide a wide range of consulting arboriculture services, such as hazard tree assessment, tree appraisal, expert witness testimony, problem diagnosis, management plan recommendations, and other consulting tasks. Companies may employ any number of Certified Arborists depending on their size and the type of work they do. This is not a complete list of Certified Arborists. Those arborists listed here have paid the PNW-ISA to advertise the fact that they offer services in these areas. While this list is organized by state/province for ease of use, many arborists cover more than one state/province. No endorsement or recommendation is granted or implied to any individual listed. A complete listing of all certified arborists is available on the Internet at: www.isa-arbor.com.
