About Us

At PSAAI, we believe that by taking the time to thoroughly evaluate patients and teach them about asthma and other allergic diseases, we lessen the time lost from school or employment and reduce the number of emergency treatments. Most importantly, the individual's quality of life and sense of well-being is improved. Our main location is in Tacoma open Tuesdays through Fridays and we have a second location in Federal Way open on Mondays. We accept most insurances, including Aetna, Cigna, First Choice Heath Network, Regence Blue Shield, Tricare, Uniform Medical Plan, United Healthcare, Premera Blue Cross and many more.
