No, I would not see Frank as a medical professional.
Yes, I think that his patients should have the opportunity (not your phrasing, I acknowledge) to know about his antics.
I think that the attention ( and search engine optimization) that this thread has generated will give those patients the opportunity.
He simply will not lose his medical license over this. Frankly, based on the comments here, I’m not even sure he actually sees patients. So the end result is that this simply means that folks who are considering using him, if any, would need to Google him to learn of this event, regardless of whether we filed a complaint with the state licensing board or not.
