Many of our members are specialty trained in neuro, obstetric, pediatric and cardiac anesthesiology as well as intensive care medicine. PAS members provide a wide range of services at Swedish Hospital (First Hill and Providence campuses) and surrounding private surgery clinics (see associated medical facilities). All medical care is provided by physician members called anesthesiologists.
