Q&A: Invitations: Addressing One to Doctors?
Q: How do you address an invitation to a doctor?
A: If a wife and husband are both doctors, the outer and inner envelopes should be addressed to: "The Doctors Rosenthal." It's that simple! If they're married but have different last names, list both names in alphabetical order on separate lines: "Dr. Rosenthal" followed by "Dr. Schwartz".If only one spouse is a doctor, list the person with the professional name first: "Dr. Kate Randolph Mr. Brian Randolph" or "Dr. Kate Randolph and Mr. Brian Randolph" (if it fits on one line).
