Psi Delta Sigma

Welcome, from the sorority sisters of Psi Delta Sigma!

.....WHO WE ARE.....

A social group of women with a primary purpose of supporting United Cerebral Palsy (UCP) in California since 1968.  We were incorporated at that time as a charitable nonprofit corporation with 501(c)(3) status.  Our fund raising efforts have led to over $2,518,984 in total contributions since May 31, 1968.  We are proud of this accomplishment and invite you to revisit our website frequently for information about the events.

.....OUR HISTORY.....

Psi Delta Sigma National Sorority was founded on February 21, 1921 in the State of Illinois. As of 1948, more than 2,500 members had been initiated and forty-four chapters organized in four states: Illinois, Ohio, California and Wisconsin. In sharp contrast, there are four chapters remaining exclusively in Southern California.

The youth of the founding members (late teens), as well as the era in which Psi Delta Sigma was founded, helps to explain the presence of the ceremonies, rituals and trappings which are normally associated with fraternal groups. While there is no denying the fact that sorority rituals, per se, must be regarded as somewhat incongruous in today's world, the original ceremonies are a portion of the heritage of Psi Delta Sigma which has managed to survive.

Originally incorporated in the State of Illinois, Psi Delta Sigma was reincorporated in the State of California on September 23, 1955 as Psi Delta Sigma National Sorority, Inc.  At that time United Cerebral Palsy/Momentum, as the organization is known today, was selected as the charity to which Psi Delta Sigma would give its total support.

Today we are Psi Delta Sigma, Inc. -- a group of social ladies with a charitable purpose. Within our organizational structure is the Psi Delta Sigma Association Grand Chapter. A single Board of Trustees serves both the social and charitable organizations: Psi Delta Sigma, Inc. and Psi Delta Sigma Association Grand Chapter.
