Gamma Tau Sigma, an Alumnae Chapter of Sigma Gamma Rho Sorority, Inc., was chartered on December 26, 1964 in Long Beach, California under the leadership of Soror Zephyr Gill, former Western Region Syntaktes.  Gamma Tau Sigma (GTS) was chartered by 10 sorors: Shirley Addison, Gervice Brown, Ethledra Claxton, Arnette Deering, Brenda Hicks, Claudia Hyman, Barbara Keesee, Merry Miles, Rosalind Mills, and Barbara L. Smith.  Gamma Tau Sigma was formed to serve as the advising chapter for the undergraduate chapter, Gamma Kappa, at California State University, Long Beach which GTS still advises today.  We have recently taken over the advisement of the undergraduate chapter, Omicron Rho, at California State University, Dominguez Hills.  Additionally, GTS serves over 60 young women and girls continuously throughout the year through our Rhoer and Rhosebud Affiliates.  Currently, GTS has an active membership of over 45 sorors and continues to grow in membership. The chapter has received a number of awards and honors including Western Region Chapter of the Year in 2019/20 and Outstanding Chapter Performance in 2022/23.
