It all began on April 5, 1895, at the University of Arkansas when four young women, with the help of a local dentist, established the secrets and symbolism that today bind over 260,000 women. This small band of women founded Chi Omega after realizing a need for an organization that would foster both friendship and respect for the potential and inherent value of women. Over the years, Chi Omega has provided its members with unique opportunities in leadership, scholarship, and lifelong friendship - striving to provide each Sister with a commitment to personal integrity, excellence in academic and intellectual pursuits, intergenerational participation, community service, leadership opportunities and social enrichment.
The Mu Lambda Chapter was established at the University of Dayton on March 31, 1990. It was formed out of the local sorority, Sigma Tau Epsilon. STE had been a local sorority at UD since 1983, but by 1989 decided that it would need to become a national sorority in order to remain strong on campus. The sisters of STE considered eight national sororities, and decided on Chi Omega in January of 1990. The first pledge class went through the sacred Chi Omega ritual and became sisters on March 31, 1990.
For the past 20 years, the Mu Lambda Chapter of Chi Omega has been one of the strongest Greek organizations on UD's campus. Participating in several campus activities, giving back to the community in numerous ways, continuing to recruit women of high standards, and winning many awards, Mu Lambda enjoys a strong tradition of excellence on campus that will surely continue for years to come.
