Grammar question When addressing correspondence to a medical doctor M.D. appears after his name what is the correct title Dr. or Mr. Thanks?

The correct title to use when addressing correspondence to a medical doctor with an M.D. after their name is Dr.

Here's why:

* M.D. stands for Doctor of Medicine, which is a professional medical degree.

* "Dr." is the appropriate title for someone who holds a doctorate, regardless of their specific field.

While "Mr." is a polite title for a man, it doesn't reflect the doctor's professional status.

Therefore, it's always best to use Dr. when addressing a medical doctor with an M.D. after their name.
