@bayarea58 Hello and welcome to Mayo Connect. I watched for a few days to see if you got a local answer to your post, but I see nobody has responded.
One way to find a doctor is to visit ntminfo.org Under the resource tab it suggests clinicians near you who specialize in NTM.
Another is to look at the Web Site of larger teaching hospitals near you to see if they treat your condition. I looked ad ucsfhealth.org because the Pulmonology Department has a good reputation. Under conditions treated Bronchiectasis is specifically mentioned.

The next step is to locate the bio for each recommended doc to be sure they list Bronchiectasis or NTM/MAC as an area of treatment. Here is one bio that might interest you - she directs the UCSF NTM clinic:
https://www.ucsfhealth.org/providers/dr-b-shoshana-zha
Even if you cannot get an appointment directly with her, perhaps you can get one with another provider within the specialized clinic.

I'm sure there are other good facilities near you. It will just take a bit of research on your part.
