Our Vision: "Women and girls have the resources and opportunities to reach their full potential and live their dreams."

"S" Club/Sigma Society


"S" Club Information


In 1966, SIA established Sigma and S clubs, providing Soroptimists the opportunity to mentor college and high school age women and girls and to instill within them a desire for volunteerism. Both high school girls and college women face unique gender bias, discrimination and challenges as they grow up and enter the working world. Mentoring girls and women through the sponsorship of a Sigma or S club, enables Soroptimists to impart invaluable support and guidance, while providing growth and leadership opportunities.  Sigma Societies are formed for college women and S clubs are for high school age girls.

Soroptimist S Club and Sigma Society Guidelines 

"S" Clubs are service clubs for high school students in our communities. They are considered "projects" of Soroptimist clubs. "S" clubs are a vital part of the high school extracurricular groups and are a great way for high school students to learn about serving others and helping in the community. The "S" clubs in Founder Region focus on helping women and girls improve their lives through programs leading to social and economic empowerment.

Founder Region has an "S" Club Committee - contact information about the committee as well as a list of the "S" Clubs at our high schools can be found in the Founder Region Roster. There is also a Facebook group for "S" Club Advisors.

For more information, contact the "S" Club Chair, Beth A. Rowe, at betharowe@yahoo.com.

Barbara Stevenson "S" Club Award

The Barbara Stevenson “S” Club Awards, specific to Founder Region, are offered solely for the purpose of honoring outstanding high school seniors that are members of an “S” Club of Founder Region. Nominations for this award are submitted by clubs with the selection to be made by the “S” Club committee.  The number and value of the annual awards are to be determined by the Region Board.
