Right and a Clinical doctor properly introducing themselves as a doctor of whatever field they are a doctor of has every right to do so. It harms no one.It should be about the patient in a hospital setting.
Again you try to make this personal. It's truly hilarious, because I don't even have an associates degree in any field.So it's a pride issue if it's simply about you and not the patient.
There is no law, in this country at least, that requires Physicians to introduce themselves as doctor. Many doctors don't.Yes. It is legally required. 'Mr.' is for surgeons.
