Welcome to the Pacific Northwest Chapter of the International Society of Arboriculture!  PNW-ISA recently launched this new website to increase the value and benefits we are providing to our members. If you are an existing member, take a few moments to familiarize yourself with the new navigation bar and information available to you. Throughout the month of September, PNW-ISA will introduce members to the various benefits that exist with this new website and integrated member database. Think networking, increased connection with our fellow arborist and urban forester community and more!  


For those who are visiting our website as a guest, welcome!  We encourage you to learn more about PNW-ISA and everything it has to offer. A lot of wonderful resources are available for students, individuals seeking a career change, homeowners, and individuals like our members who share a common love for TREES.

While 2020 has thrown many challenges our way, PNW-ISA is taking this opportunity to focus on its purpose and how we can improve the way we interact, engage and support our members. Stay tuned for more information and enjoy the new PNW-ISA website.
