But I did not exactly answer your question. Yes this person evidently has a PhD and teaches about hearing or a lack of it. But when I asked the telephone scheduler about credentials for this “ Dr” the scheduler told me the familiar “just go online about Mayo and look it up.” Well, thinking it was a medical doctor, I could not find this person and figured she must be new. I called the telephone scheduler back and she said “Oh you must have spelled the name wrong as it ends in z and not s”. So, I felt I was being shuffled off to some new person which is true, and I cancelled. Have any suggestions?
