This caught my eye recently in a GUM dental products commercial. If you are going to refer to someone by their title, i.e., John Smith, DDS, you do not include “Dr.” at the front, so the reference to this dentist is incorrect. The same rule applies to the title Esq. If you say John Smith, Esq., you do not add “Attorney” to make it Attorney John Smith, Esq. Choose one or the other, but do not use both.
