  • On second reference: Dr.
  • Not a doctor: Use Mr. or Ms. on second reference. 
  • Use of first name acceptable in direct quotes. 
  • When referencing institution after title, the inclusion of city and state is not necessary for major institutions: “Samuel Smith, MD, professor of pediatrics at Johns Hopkins University School of Medicine.” 
  • Rep., Reps., Sen. and Sens. as formal titles. Spell out, lowercase representative and senator in other uses.
