Chi Delta Theta Sorority is an Asian-American interest sorority that was established on October 13, 1989 at the University of California at Santa Barbara by founding mothers Miss Alison Suto-Stripling and Miss Joanne Yamaoka. Over the past sixteen years, Chi Delta Theta has expanded to include four other chapters and over 100 active sisters all over California.

The Beta Chapter of Chi Delta Theta was officially founded on February 3, 1992 with ten founding members at the California Polytechnic State University at San Luis Obispo (Cal Poly SLO). As with UCSB, the Beta Chapter was the first Asian-American interest sorority on the Cal Poly campus.

Every year, the Beta Chapter participates in several events through­out the community, in­clud­ ing Howl­-o­-ween Hoopla, the MS Walk, Open House, and Culture­Fest. In addition to these events, we host, in conjunction with the Omega Xi Delta Asian­ Interest fraternity, the annual Lantern Festival.

The sisters of Chi Delta Theta strive to promote sisterhood, academics, community service, cultural awareness, and social activity in the lives of its members. Together, our goals are to unite Asian clubs and organizations, to educate and enhance the learning of Asian culture to the university community, to encourage in­ter­action between cultural fraternities and sororities, and to provide a support network for our members by developing a special bond of sisterhood, loyalty, and commitment.

Now, over a decade later, the sorority has not only prevailed, it is thriving and the spirit of sisterhood is alive at the University of California at Santa Barbara, Cal Poly San Luis Obispo, Loyola Marymount University, Cal State Long Beach, and the University of California at Davis.
