What is proper salutation for doctor?

When addressing a doctor, the proper salutation is "Dr." followed by their last name. For example, if the doctor's name is John Smith, the salutation would be "Dr. Smith." If the doctor has a medical specialty, such as cardiology or pediatrics, you may also include the specialty after their name. For example, if Dr. Smith is a cardiologist, the salutation would be "Dr. Smith, Cardiologist."

In formal correspondence, such as a letter or email, you should also include the doctor's title and any other relevant credentials. For example, if Dr. Smith is a professor of medicine, the salutation would be "Professor John Smith, MD."

When addressing a group of doctors, you can use the general salutation "Drs." followed by their last names. For example, if you are addressing a group of doctors who are all cardiologists, the salutation would be "Drs. Smith, Jones, and Williams, Cardiologists."

It is important to use the proper salutation when addressing a doctor, as this shows respect for their profession and expertise.
