Dr. Mary Smith and Mr. James Doe
You write “Dr and Mrs. Smith”
Mr. and Dr. Joseph Smith (indicates the wife is the doctor)
The address should read: Drs. John and Jane Doe or, Dr. John Doe and Dr. Jane Doe.
When addressing an envelope to the wife of a doctor who is not a doctor herself then and he is Dr. John Doe, then address the envelope to her as Mrs. John Doe or Ms. (Mrs.) Jane Doe.
dr Mary smith would be the correct way
There are two ways to address a female doctor and her husband formally: * If it's a friendly get together then you could address them to each guest as 'This is Dr. Mary Jones and her husband Jack. * If it very formal then introduce them as Mr. Jack Jones and his wife Dr. Mary Jones.
The address should read (an example): Dr. John Doe and Mayor Jane Doe.
As Mr & Mrs.
Dr. [Husband's Full Name] and Dr. [Wife's Full Name]
Dr. and Mrs.............
You address the husband who isn't a doctor and the wife that is as: Mr. John Smith & Dr. Jane Smith It is protocol that the Mr. comes first and not necessary to put the female doctor's name first.
