@EmilyGreen,
I don't know if this is always the case, but every PA that I've seen refers to herself as "Doctor" so and so, and the office staff refers to her as "Doctor" so and so, and on the prescription bottle it shows it's been prescribed by "Doctor" so and so. Hey folks, I don't know what you want to call this, but I call it fraud. The first thing that comes to the mind of the average person is that the PA is an actual medical doctor. This kind of misrepresentation is yet another scam of the medical/pharmaceutical industry. Enjoy!
