Our Story

Northwest Asthma & Allergy Center (NAAC), as it is known today, began as an allergy specialty clinic in 1964.

Then under the direction of C. Warren Bierman, MD, and William E. Pierson, MD, the practice first focused on serving pediatric and adolescent patients. For many years, we also enjoyed the leadership of Gail G. Shapiro, MD, who was the first woman elected to be the President of the American Academy of Asthma, Allergy and Immunology (AAAAI) and is dearly missed.

Over the years, NAAC expanded beyond pediatrics to serve patients of all ages, allowing all family members to be seen for allergy and asthma care in a single location. We continue to grow in new ways in our efforts to serve Washington’s allergy and asthma needs; today you’ll find NAAC offices across the state, including Seattle, Redmond, Everett, Renton, Issaquah, Mt. Vernon, Richland, and Yakima.
