Our Physicians and Providers
Michael J. Barrett, MD, FAAAAI

Native Oregonian (Albany) glad to be back in my home state.   Trained in Clinical
Immunodeficiency at Duke, I joined Kaiser Permanente to work in Allergy alongside some
fantastic physicians that I really respected (Kuo Chang was one of them!)  My years with
Kaiser included caring for adult and pediatric allergic disorders, as well as
immunodeficiencies.  I have two wonderful adult children living in Oregon, a fantastic wife of
37 years, and a dog.  I enjoy medical practice, running, swimming, biking, backpacking and
jazz music.
