Welcome to the Sigma Kappa, Zeta Kappa website! Since 1977, the Zeta Kappa chapter at Angelo State University has been bringing women together and providing social and intellectual development. The ladies of Sigma Kappa represent a tremendously diversified group. Each Sigma possesses her own sense of individuality and as a whole; Sigma Kappa maintains the highest standard of sisterhood. Our women take part in academic as well as social and philanthropic events, ranging from honor societies to intramural sports. Each Sigma Kappa is able to contribute her own qualities which enrich the sorority as a whole.
