What Sigma Kappa Sorority does
Sigma Kappa Sorority is a 501(c)(7) not-for-profit women's sorority founded in 1874 at Colby College in Waterville, Maine, and headquartered in Carmel, Indiana. The organization serves more than 230,000 initiated members worldwide through 115 collegiate chapters at U.S. universities and 83 alumnae chapters, delivering lifelong membership benefits across collegiate and post-collegiate life stages. Its core product is a structured sisterhood experience emphasizing friendship, personal growth, leadership development, and service, delivered through three interconnected entities: the Sorority (membership operations), the Sigma Kappa Foundation (scholarships, grants, mental health and career funding), and the National Housing Corporation (housing operational and financial support).
The organization generates revenue through a diversified set of streams: recurring collegiate national dues and fees (new member, badge, initiation, housing, liability, and technology fees), annual alumnae national dues at $35, licensed merchandise royalties through ShopSigmaKappa.com and Herff Jones, affiliate revenue from wine partnerships (One Heart Cellars and One Heart Napa Valley with 20% of proceeds to Foundation), travel program revenue via Adventures with Heart with EF Go Ahead Tours, and convention registration ($175-$800). Digital infrastructure is built on the Higher Logic platform powering sigmakappa.org and the Dove Hub member portal, with payment processing through CardPointe and virtual ceremonies via Zoom.
The member experience is increasingly delivered through digital and partner-enabled services: the YOU at Sigma Kappa self-guided well-being platform, Talkspace online counseling (free for undergraduates, discounted for alumnae), Careerhouse career development (free through Foundation funding), Active Minds mental health resources, and the Financial Head Start Podcast. In 2024, Sigma Kappa completed a brand refresh introducing new colors (Mary Maroon, Legacy Lavender, Dove Love), an updated visual identity, and the "with heart" tagline. The organization operates without external investors and is governed by a National Council of volunteer members supported by professional staff.
