Gamma Sigma Girls

Founded in 2010, Gamma Sigma Girls® is a unique leadership development program offered by Girl Scouts of Southwest Texas in partnership with area school districts. It combines the proven outcomes of the Girl Scout Leadership Experience with a “sorority-type” setting, targeting teen girls in high school who have a limited history of Girl Scouts in their family or the community.

Similar to a sorority, Gamma Sigma Girls® (GSG) will bring girls together through the bond of sisterhood and allow them to explore common interests in a safe space. Unlike other extracurricular activities at school, GSG does not require members to have a special talent, skill or minimum GPA.

You just have to be a girl. That’s it!

Gamma Sigma Girls® serves nearly 800 teens in 17 high schools and nearly 1,000 girls in 19 middle schools in San Antonio ISD, Harlandale ISD, Southwest ISD, Edgewood ISD and Uvalde ISD. In the tradition of sororities, Girl Scouts of Southwest Texas introduces Gamma Sigma Pearls, which is a younger “sister chapter” of Gamma Sigma Girls® named after a jewel significant to the Girl Scout movement. 

As Gamma Sigma Girls® and Gamma Sigma Pearls, teens will choose to focus on one of three areas: advocacy, taking action, and being college bound.


Advocacy: Girls will identify a cause they are passionate about and work toward effecting social change.


Take Action: Girls will become positive change agents in their community when they participate in service projects that benefit the world around them.


College Bound: Girls will explore opportunities to help them decide on a career path, and work toward achieving a higher education.

The nearly 1,800 new and returning members of Gamma Sigma Girls® and Gamma Sigma Pearls were inducted at formal Investiture and Rededication ceremonies at the beginning of the school year.
