Sigma Sigma Sigma National Sorority

What Sigma Sigma Sigma National Sorority does

Sigma Sigma Sigma National Sorority ("Tri Sigma") is a private, nonprofit women's membership organization founded in 1898 and headquartered in Chapel Hill, North Carolina. It operates as one of 26 member sororities of the National Panhellenic Conference, serving collegiate women at universities nationwide through campus-based recruitment and a lifelong alumnae chapter network. The organization's mission is centered on five guiding values — wisdom, power, faith, hope, and love — and it is governed by an elected Executive Council with operational support from a National Headquarters staff of 11-50 employees.

Tri Sigma's core technology asset is Sigma Connect, a members-only web portal that handles alumnae dues payment ($50/year annual or $1,898 lifetime), recruitment information, chapter operations, officer resources, and member communications. The organization publishes an annual print magazine (The Triangle), a dues-payer newsletter (The Sigma Scoop), and a senior-alumnae publication (Golden Glimpses), and distributes branded merchandise through the Purple & Pearls boutique, the Affinity Marketplace, and Herff Jones as official jeweler. Program offerings include The Academy, Competency Certifications, Virtual Leadership Seminars, the Health Promotion Program, and Mental Health First Aid, with scholarships and programmatic funding administered by the Tri Sigma Foundation, which in 2025 launched its first comprehensive $10 million capital campaign.

Revenue is generated from three streams: (1) recurring alumnae dues (annual and lifetime subscriptions), (2) tax-deductible donations to the Tri Sigma Foundation, and (3) merchandise sales. The Foundation's $10M campaign — "They Did. You Can. We Will." — had raised $8,612,813 as of February 1, 2026, with 68% in deferred estate gifts. The sorority also maintains a decade-long philanthropic partnership with the March of Dimes. No public API, no AI/ML capabilities, and no third-party technology integrations are documented.
