Sigma Lambda Gamma National Sorority, Incorporated (), also known as Gammas or SLG, is a national sorority. It was founded on April 9, 1990, at the University of Iowa in Iowa City, Iowa by five collegiate women who wanted an organization to empower Latina women. The sorority focuses on five principles: academics, community service, cultural awareness, social interaction, and morals and ethics. Having expanded to more than 235 entities in less than thirty years, membership is open to any individual, who identifies as a woman or nonbinary, and who meets the membership requirements, regardless of religion, race, or nationality. Individuals may join through undergraduate chapters at a college or university, or after acquiring a college degree through an alumni association. History In the fall of 1989, a group of women met to form an organization that would empower women from every culture. By April 9, 1990, the University of Iowa Panhellenic Council officially recognized the organization as a sorority, which Sigma Lambda Gamma celebrates as its founding date. The five women who were instrumental in establishing the organization–Gloria Cuevas, Julieta Maria Miller, Maria Ester Pineda, Danell Marie Riojas, and Guadalupe Temiquel–are collectively referred to as the Five Founding Mothers. A national headquarters was initially established at 900 West Penn Street in North Liberty, Iowa. They later moved to their current address at 1295 Jordan Street, Suite 3 in North Liberty, Iowa. Along with housing national records and staff, it was also home to the sorority's national biannual publication, La Mensajera. The Omega chapter was later established to recognize and pay respect to deceased sisters. As the sorority grew, Sigma Lambda Gamma's membership became more multicultural. In acknowledging this, the organization, which was a part of the National Association of Latino Fraternal Organizations (NALFO) from January 2001 to May 2010, left due to a desire for autonomy and due to its increasing multicultural membership. The sorority celebrated their 100th and 101st chapters simultaneously with the addition of the Theta Delta chapter at Columbia University and the Iota Delta chapter at Millikin University in 2010, having expanded to more than 100 chapters in twenty years. While chapters have always organized local programming on their respective campuses, Sigma Lambda Gamma later created the Education Foundation. The Young Women’s Leadership program was designed to promote confidence and leadership skills for middle-school aged girls. An emotional intelligence education program was also started up.
