Eta Mu began as local sorority Delta Pi Kappa. The local's mascot was a lion, and they supported Big Sisters of America. In January 1988, the local was colonized and Eta Mu was installed on May 7. The chapter rented a house, but a city ordinance forced out Greek houses that were not owned by the national organization. The chapter held meetings at the Student Union and contributed to the Ronald McDonald House in Sacramento and has a commemorative brick in the main walkway leading to the house. The chapter regularly held recruitment events around the pool at the home of former Grand Council member Joan Sutton Knox, Psi - UC at Berkeley. A niece of Grand President Mabelle Fuller Sperry, Sally Stone Berlant, Delta - Texas, was instrumental in establishing the chapter and served for many years as an advisor. A founding member, Karen Mitchell, designed the 150th anniversary logo. The chapter closed due to low numbers in 2005. Suzanne Nelson Kennedy is a long-serving international officer.
