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