when a single dr marries, is her name still dr with new name

Yes — she can still use Dr. with her new married name, and many women do. The title is tied to the qualification, not to the surname, so changing your last name after marriage does not automatically remove “Dr.”

How people usually write it

Common formats include:

• Dr. New Surname.
• Dr. Maiden Name.
• Dr. Maiden-Husband Surname, if someone chooses a double surname.

The choice is usually personal and can differ between professional and social use. Some doctors keep their maiden name professionally for continuity, while using their married name in everyday life.

Practical note

If she changes her legal name, she may need to update records such as passports, licenses, and professional registrations, depending on local rules. In some settings, a marriage certificate plus proof of qualification may be enough to link the old and new names.

Example

A physician named Dr. Smith who marries Mr. Jones could be:

• Dr. Jones, if she changes her surname.
• Dr. Smith, if she keeps her professional name.
• Dr. Smith-Jones, if she uses a combined form.

TL;DR: being married does not stop someone from using “Dr.”; the surname can change, but the title still remains.
