Our Chapter 

In 1966, Chi Delphia was formed as a little sister program to Delta Chi Fraternity at Cal State-Sacramento. In 2001, after changing its name to Chi Delta, the organization established a chapter at Sonoma State. The campus opened for extension in 2007 and Alpha Delta Pi was selected to affiliate with the members of Chi Delta, forming the sorority’s 12th California chapter. 

As a colony, they helped decorate the Ronald McDonald House for the holidays and made cookies. They were the first Greek organization to pair with the Cotati Community Center for an event for 200 local children. They held leadership positions in Associated Students and JUMP, a campus service organization. In November, at the chapter’s installation at Sonoma State, seven Chi Delta alumnae were initiated along with 79 Alpha members.

Our Sorority represents a group of diverse people who always strive for the highest level of excellence, as our founders intended. Shared goals and interests in areas of service, academics, and building solid relationships hold our chapter together and define who we are.
