A question, doc

Dear Dr. Donohue: Can you tell me what a PA is? My wife could not see our regular doctor, so they made an appointment for her with a PA. It turned out really well; she was efficient and nice. — W.C.

Answer: A PA is a physician’s assistant. It’s a college-awarded degree, and the training is quite rigorous. PAs work under a doctor, but are independent in their role of diagnosing and treating illnesses. They have become valuable members of the profession.
