Lambda Sigma Gamma Sorority is a fairly young organization chartered March 11, 1986 and founded October 24, 1986 on the campus of California State University, Sacramento. It was founded by 27 women who were seeking to make university life less lonesome and more supportive. Our Founders realized that much of the difficulty in forming a Sorority came from the students’ unfamiliarity with the Greek System. Most people of Latin, African, Asian, and Native American descent had not been a part of the University institution for very long and many still did not comfortably fit in with the University atmosphere.

Xi Chapter
A lack of contentment found on existing sororities at the UCR campus led a group of women in search of one of their own. After much research one was found to meet all needs. Lambda Sigma Gamma Sorority encompassed a remarkably sisterhood. It encircled many aspects of university life such as academic, community, and social aspects. As prospective members, this group of women became known as Ladies of Cultural pride. Throughout the summer of 2000, the ladies met on a weekly basis and participated in many events with local LSG chapters. On November 18, 2000, Lambda Sigma Gamma Sorority, Inc. was founded on the UCR campus by seventeen women. Now, the Sisters of Xi Chapter continually work hard to uphold the visions that Lambda Sigma Gamma Sorority was founded upon. Xi Chapter continues the tradition that was passed on to us by our Chapter's Founding Mothers.
