No, it is Dr. and Mrs. Ramesh
"Dr and Mrs Smith" is the correct salutation. (With Smith replaced with the correct surname)
The correct way to format the title Dr. and Mrs. Young is with periods after "Dr." and "Mrs.", as shown here.
I BELIEVE THE CORRECT FORM WOULD BE: DEAR DR. AND MRS .....
If the doctors name was Steven Smith, the correct form would be "Dr and Mrs Steven Smith".
Dear Dr. & Mrs. Smith
is is correct to use Dr. Mrs. for a female doctor?
Dr. John Smith and (Ms., Mrs., or Dr.) Jane Smith
Yes you should always do that
Mr and Mrs is correct or Mrs and Mr is correct
* Dr. & Mrs. John Doe
If the wife has taken his surname then "Dr & Mrs James King".... or possibly "Dr James & Mrs Susan King". If she has retained her maiden name then "Dr James King & Ms Susan Jones".
