Gamma Rho Lambda, Alpha Chapter, was founded in the Fall of 2003 by 12 original members at Arizona State University in Tempe, Arizona. The sorority was established as a social support system for lesbian, bisexual, transgender, and alternative lifestyle-friendly female students. Embodying an open and diverse environment for all of its members, the sorority strived to break down barriers between the LGBTQ community and the greater community.

In 2005, Gamma Rho Lambda began the daunting task of expanding nationally, as they had been approached by several interested women on other campuses in the United States. Over the course of the next year, Gamma Rho Lambda worked to expand to these campuses, functioning in a national and local capacity at the same time.

In 2006, with enough alumni members to support a national council, Gamma Rho Lambda National Sorority became independent of Alpha Chapter. Since then, Gamma Rho Lambda National Sorority has been working not only on expansion, but also adjusting to the needs of our chapters and members, working to establish a Foundation, and bettering the community overall through these efforts.
