    Dr. Duffy was very good at explaining what was to take place during my visit and very interested in my care and well being both during my visit and after I went home to recover.

    Dr Duffy is not only a good listener, but has the ability to explain medical terms that a layman can understand.

    I hope I don't have to have any more Mohs surgeries but if I do DR Duffy would always be my first choice. He explains the procedure so clearly and is very carrying and most of all a terrific surgeon.
