In November 2012, a group of sorors conceived the idea of establishing a new graduate chapter of Sigma Gamma Rho Sorority, Inc. in the city of Round Rock, TX. Round Rock, was the home of a growing African American community, attracting new industries and embarking upon ambitious renovation and expansions of its downtown areas.
The women saw a need for increased participation from community organizations in the development of the city and betterment of its citizens. Since many of them were young women with young families, they had a vested interest in assuring that support services were available to the city's community, particularly African American youth.
An intense effort began to contact sorors, who would be interested in working with the group to form the new chapter. On July 26, 2014, Maureen Oyiriaru, Virginia Pearson, Venice Taylor, Tawanda McCall, Eva Marlene King, Carmina Hill, Shanea McGee and Jennifer Beckford, chartered the Magnificent, Motivated, Mighty Mu Beta Sigma Chapter, Sigma Gamma Rho Sorority, Inc
Mu Beta Sigma continues to grow. In November 2015, the Chapter welcomed it's first T.O.R.C.H. Class, the 6 Golden Goddesses. Each year thereafter, MBS added another of T.O.R.C.H. Class from Fall 2016 - Fall 2020:
