From Katherine's file cabinet (there is a link below these recommendations; however, you could also call one of these doctors and ask if they would have a recommendation in your area which is why I left them in this post):

DOCTORS-NYC From membe @ehliny: outstanding pulmonary doctor in NYC: Dr. Louis de Palo at Mt. Sinai Respiratory Clinic: (212) 241-5656. I also have a first-rate GERD doctor in Dr. Jonathan Aviv, 210 East 86th St: 212-722-5570. Dr. de Palo is not quick to prescribe antibiotics if you don’t show full range of MAC symptoms. Dr Aviv (and I) believe there is a strong association between gastric reflux and lung disorders. I have a lot of confidence in both these physicians. Dr. Timothy Aksamit at MAYO Rochester had also recommended a NYC doctor for MAC, Dr. Doreen Adrizzo Harris, at NYU Pulmonary Medicine.

DOCTOR-FINDING A GOOD INFECTIOUS DISEASE DOCTOR https://www.ntminfo.org/patients/physician-referral-list move down the page to YOUR STATE

INFECTIOUS DISEASE DOCTOR
1.GOOD Infectious Disease doctor locally. Just google it
2. call the various offices .. ask to speak to a nurse .. ask 'How many MAC patients has your doctor seen in the past 12 months?' If a NURSE in the office does not even KNOW what MAC is .. that is a pretty good tip off that office does NOT treat MAC patients!
3. Request an appointment with the BEST ID doctor locally you can find
4. I would collect AN/Y/ALL medical records I could get my hand on from ANY/ALL doctors you have seen. It may take them emailing you Authorizations for Release of Information .. BUT DO get started.
5. Having read ALL the back pages of this Forum .. done your 'due diligence' .. educating yourself .. you will NOW have a LONG page of questions and will KNOW exactly WHAT the ID doctor SHOULD be doing for you .. or NOT doing.

Hope this helps you, Laura!
