California State University at Fullerton, February 28, 1970
Members of Delta Chi Delta, a well-established local sorority had won many honors before becoming Zeta Alpha chapter in 1970 with 24 collegiate and 17 alumnae initiates. The chapter house at 2207 E. Commonwealth Avenue had a swimming pool in the backyard that often served as a site for chapter events. Sometime in the early 1990s, the pool was filled in; however the large yard still serves as a site for many chapter and recruitment activities. Zeta Alpha prides itself on philanthropic work, supporting the Ronald McDonald House and Camp Titan, the university's philanthropy. In 2000, they received the "Most Money Raised" award for Camp Titan for the 14th consecutive year. Karen Mayster Gans who served as Chair of the Chapter Finance Directors had a long record of service as does Cynthia "Cindy" Voris.
