Betty attended William Woods College in Fulton, MO, and DePauw University, where she joined Gamma Chapter. She earned a Master's Degree from DePauw before moving with her husband to Arizona. Her two daughters, Sara "Buffy" and Jody, are both Alpha Phi members of Gamma Chapter.
In 1959, Betty was appointed chairman of the Fraternity's Standards Committee. She served as Alpha Phi's International President from 1970 to 1974. From 1974 to 1990, she served as delegate to the National Panhellenic Conference. From 1980 to 1984, she served two terms as president of the Intrafraternity Research and Advisory Council. She gave over a thousand speeches to businesses, civic and Greek letter groups and published several books, including Beyond the Hills (1944) A Code for the Coed (1962) and A Goodly Heritage: The Collected Works of Betty Mullins Jones (1992).
Among the honors Betty received were an honorary degree and the Green Owl Award for Outstanding Alumna from William Woods College; an Alumni Citation for Outstanding Achievement from DePauw University; the Jack Anson Award from the Association of Fraternity Advisors; Kappa Delta's Order of the Diamond Award for service to the Greek World; the College Fraternity Editor's Evan C.

"Nobody ever did and nobody ever will love Alpha Phi more than Betty Mullins Jones," said her daughter, Jody Jones Serey.
