On March 11. 1986, Lambda Theta Nu Sorority, Inc., became the first Latina Greek Letter organization to be established on the west coast.  It was founded by 18 Latinas from diverse backgrounds.  Since then, we have kept close to our hearts the ideals set forth by our Founding Mothers as the foundation of our organization: academic excellence, service to the Latina/o community, cultural awareness, and sisterhood. Through these ideals we have strengthened our sisterhood which now includes 27 chapters in 5 states. 

The Sigma Chapter of Lambda Theta Nu Sorority Inc. was established at the University of California, Irvine on April 1, 2001 by 9 diverse women pursuing a higher education.  Six years later, Sigma chapter consists of 40 ladies from majors in Social Science, Social Ecology, Biological Sciences, Engineering, Information and Computer Science, Mathematics, and Art. 

The purpose of Lambda Theta Nu Sorority, Inc. shall be to open doors of opportunity to the Latinas of our community.  Our primary focus is academic excellence and meeting the needs of Latina women in higher education.  Lambda Theta Nu Sorority, Inc. also promotes the advancements of Latinas through various campus

activities and community services, and provides

an environment for personal growth within a unit

of Sisterhood.  Lambda Theta Nu Sorority, Inc.’s

priorities, however, will be placed upon academic

 excellence and community service.
