About

SIGMA, a non-profit women’s organization, is dedicated to the general improvement of the Fond du Lac community. SIGMA members collectively support a multitude of individuals, organizations, and community events with their time, talents, and fundraising efforts.

SIGMA was formed in 1931 as a literary group. Over time, the group evolved into a service organization to help families in the Fond du Lac community. As need arose, SIGMA expanded its involvement to include organizations and community events. The potential to make a difference in the community has, and continues, to unite SIGMA members in support of a common purpose. 

Today, SIGMA’s 35 active members meet on the first Wednesday of each month from September through Mary, continuing the tradition of community service.
