If you have a pulmonologist or pulmonology group you want to see, call and ask who is experienced. For an individual doctor, look up their profile, which will show their certifications and areas of interest or specialty. Otherwise, check with your nearest teaching hospital or medical school for a referral.
I f you happen to be near a Mayo Clinic (Rochester, MN Jacksonville, FL or Phoenix, AZ) National Jewish Health (Denver, CO) or University of Texas, Tyler all have excellent Bronchiectasis/MAC treatment centers.
