Founded at USC in 1948, Cal­i­for­nia Delta has long been a sym­bol of suc­cess for Phi Delta Theta on the west coast. Being one of the larger chap­ters at USC through the 60’s, 70’s, 80’s, and 90’s, Cal Delta returned USC in 2005. Begin­ning with a re-founding class of 35 mem­bers, Cal Delta is now a well-decorated chap­ter of 90 mem­bers and the model for future Phi Delta Theta chap­ters around the United States.
