Mary Louise Williams was the eleventh president of Beta Pi Omega Chapter. Her tenure was from January 1969 - December 1971. She was also the thirteenth South Central Regional Director installed at the Denver Boule (National Conference) in 1972 to serve through 1974. Williams was initiated into Alpha Iota Chapter at Lincoln University in Jefferson City, Missouri, where she received her B.A. in Music. She holds two Master's Degrees—one in Education and the other in Administration from the University of Arkansas at Fayetteville. During her tenure as President, Williams encouraged larger numbers of members to attend conferences, formed the TRI Council which organized sorors statewide, and organized the benevolent committee that now functions to extend courtesies to sorors. She said at that time it was called “Bridging the Gap of our Sisterhood.” Her tenure as Regional Director involved and affected Beta Pi Omega in a very positive way. This is when we became known as one of the premier chapters in the South Central Region. Williams recounted, “ I first appointed an Assistant to the Regional Director— Dora Tatum Robinson, an undergraduate from Alpha Rho, University of Arkansas at Pine Bluff.” Dora was an honor student—this helped to win the undergraduates over. Williams chartered seventeen chapters—three in Arkansas—
Theta Mu Chapter at the University of Central Arkansas in Conway; Theta Eta Chapter at Henderson State College in Arkadelphia; and Eta Upsilon Chapter at Arkansas State University in Jonesboro. Beta Pi Omega members traveled with her to visit sister chapters and to conferences. Janet Davis Tate attended her first Leadership Conference with Williams in Chicago, Illinois. Sammie Tollette and Fon Nelson traveled on many of the chapter visits. Williams made a point to place all Beta Pi Omega members attending Regional Conferences on one or more of the Regional committees. Everywhere she traveled, she would speak positively about Beta Pi Omega. Williams also served on the International Standards and Membership committees.
