Mr. Aaron Oforlea | Gina Tartaglia, MD |
Dr. Edward Davies | Jamie Barlow Kayes, PhD |
Most other titles—
Rev. Franklin Graham | Reverend Graham |

Use either a title or an academic degree, but not both, with a person’s name. Instead of Dr. James Dillon, PhD, write Dr. James Dillon or James Dillon, PhD. (Note that academic degrees such as PhD and RN often appear without periods; see 56a.)
