NPSA History
In the annals of medical history in the Pacific Northwest the foundations of medical meetings is the illustrious North Pacific Surgical Association. Born of collective ambition and shared expertise, its genesis sparkled in the city of Portland on that auspicious day of March 6, 1912. Yet, it was in the vibrant heart of Seattle, on the storied date of May 12 of the same year, where the symphony of organization reached its crescendo.
From those inaugural moments of unity and purpose, the NPSA has unfurled its banner of excellence that traverses the tapestry of the Pacific Northwest. With each passing year, this esteemed assembly rotates gracefully between the urban jewels of the region, enriching the medical landscape and forging bonds that stand as monuments to the relentless pursuit of surgical excellence.
