Alpha Phi Alpha was introduced to San Diego at the University of California, San Diego in September of 1972. The undergraduate chapter, known as Eta Sigma, the 370th chapter, is the Metropolitan chapter of San Diego. Eta Sigma continues to uphold the high standards of Alpha, which strives for excellence in academics, leadership, and community service.

From 1992 through 1994, in 1996, and in 2000, Eta Sigma was chosen as Alpha Phi Alpha's Western Regional Chapter of the Year. Winning Chapter of the Year consists of many different competitive categories. We feel as though even if we don't win, we have given something back to our community.

Eta Sigma has been constantly supportive of the African American community at SDSU and UCSD, as well as the San Diego community at large. With programs ranging from AIDS Awareness to the Gospel Extravaganza (which raises funds for our annual Barron McCall Scholarship Award), Eta Sigma has continued to hold up the light.
