Sigma Lambda Alpha Sorority, Inc. is a Latina-founded organization and is open to all women regardless of race, nationality, or religion.

[1] Sigma Lambda Alpha Sorority, Inc. (ΣΛΑ), otherwise known as Señoritas Latinas en Acción, was founded in the summer of 1992 by Angeles Gonzalez.

She promptly received a response and was advised to begin an interest group, elect officers and choose an organizational name to start the sorority process.

With the interest group of Sigma Lambda Alpha established, excitement grew with the thought of having Latina representation at TWU, however the sorority in Pennsylvania decided against beginning a chapter in Texas, because of the distance between the two states.

They elected to carry on the name of Sigma Lambda Alpha/Señoritas Latinas en Acción Inc., and created a sisterhood on the basis of cultural awareness, community service, leadership and academic achievement.

The mission of Sigma Lambda Alpha Sorority, Inc. is to promote the importance of community service involvement and academic achievement as well as to educate and excel the stance of Latino cultures in this diversely enriched society.

The sorority's principles or pillars are Community service, Academic achievement, Cultural awareness, and Sisterhood.
