Gamma Sigma Girls

Gamma Sigma Girls is a unique leadership development program offered for the second year by Girl Scouts of Southwest Texas in partnership with area school districts. This pilot program 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 more than 350 teens in 12 high schools in San Antonio ISD, Harlandale ISD and Edgewood 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. In its inaugural year, Gamma Sigma Pearls will serve more than 100 girls in middle school campuses in Harlandale ISD and Edgewood ISD.

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 450 new and returning members of Gamma Sigma Girls™ and Gamma Sigma Pearls were inducted at formal Investiture and Rededication ceremonies earlier this year.
