Theta Epsilon Sigma Alumnae Chapter was organized under the auspices and vision of past Western Region Syntaktes (Director), Dr. Gwenette Parker, on June 2, 1996, in the municipality of Culver City, California. Sorors who joined together in their quest to make Theta Epsilon Sigma a reality were charter members:

• Soror Keeshawn Andrew

• Soror Sasheen Artis

• Soror Renee Culpepper Rawles

• Dr. Wendy Flenoury Talley

• Soror Kesia Irvine

• Soror LaTonya Theus Nelson

• Dr. Gwenette Parker

Theta Epsilon Sigma is responsible for the organization of three undergraduate chapters: Xi Rho at the University of California Riverside, Omicron Mu at California State University Fullerton and Omicron Rho at California State University, Dominguez Hills. We also currently advise undergraduate chapters Theta Epsilon at the University of Southern California  and Tau Alpha at California State University- Los Angeles.

In January 2003, Theta Epsilon Sigma started a Rhoer Club and, in 2005, started a Philo affiliate chapter.

Theta Epsilon Sigma is known for being the chapter that is moving and shaking in the name of Sigma. Our goal is to increase public awareness of the Sorority's programs by establishing linkages between other community organizations, political leaders, government agencies, corporations, and local businesses. 

Theta Epsilon Sigma is a part of the Mighty Western Region of Sigma Gamma Rho Sorority, Inc.
