@bonniewhite56 Bonnie, I have been seeing Dr Kukhon who is working as a "fellow" under Dr Margaret Johnson. I saw Dr Johnson on my first visit then follow-up was with Dr Kukhon. I was impressed with both doctors, they were well versed with Bronchiectasis and Mycobacterial lung infections. Dr Kukhon will be leaving Mayo clinic in June 2022 for a more permanent position somewhere else. In my opinion Mayo is not going to hire anyone but the best in their field. Bill
