The IIDA Northern Pacific Chapter seeks to uphold the highest standards for the professional practice of Interior Design in the states of Washington, Idaho and Alaska, as well as British Columbia and Alberta.
With a primary focus on Education, Advocacy and Outreach, the Chapter supports designers at all stages of their careers through scholarships, personal enrichment opportunities, connections to both the local and global design community, and ongoing support for the legal recognition of the commercial interior design profession.
