Here’s a troubling story from the Mayo Clinic in Phoenix. A man who asked to see a physician ended up seeing someone who looked the part of a physician but in fact was not even a nurse or a physician’s assistant. In reality, he had no certification whatsoever to be “practicing” medicine–yet, he was, and at the Mayo Clinic at that.
Fake “docs” at the Mayo Clinic

COMMENT:
Remember the battle cry folks: Caveat emptor.
Never make ANY presumptions about the practitioner you are seeing for the first time.
