Hello, if you don't get a recommendation here, another thing to try is their internal "Request an Appointment" feature. Search for pulmonologists, click on the "Request a Call...", fill it out, specifically explaining all of your lung issues & leave the physician name blank. When you get the call back, press for someone with bronchiectasis experience. The caller may need to go back to the department to find out exactly the right doc(s) for you.

This has worked for me in finding a new hand surgeon and finding the right rheumatologist for my husband's rare type of arthritis.
