Delta Zeta Sorority

What Delta Zeta Sorority does

Delta Zeta Sorority is a private, nonprofit women's membership organization founded on October 24, 1902 at Miami University in Oxford, Ohio, by six undergraduate women. The organization operates a decentralized chapter-based model with 162 collegiate chapters in the United States and Canada and over 180 alumnae chapters across 49 states, the United Kingdom, and Canada, organized into 13 collegiate regions and 8 alumnae areas. At any given time it serves roughly 15,000 undergraduate members and maintains an alumnae network of more than 315,000 initiated women across its 123+ year history, with approximately 1,200 alumnae currently serving as collegiate chapter advisors.

The membership experience is delivered through a digital ecosystem that includes an online Learning Center (LMS) for officer and volunteer training, the Truly Connected suite (TC Grow mentorship/job-board platform, TC Gather in-person networking, TC Share virtual discussion groups), the Clutch risk-prevention planning app, a member portal, and the National Historical Museum in Oxford, Ohio with virtual tour capability. Marketing and engagement channels span The LAMP magazine (published since 1910), the Truly Blog, the Women We Know podcast, organic social, email, the biennial National Convention, the annual Norma Minch Andrisek Leadership Conference, Everlasting one-day sisterhood events, and the Alumnae Travel Series.

Revenue derives from chapter-set membership dues, $350 alumnae initiation fees plus badge purchases, biennial convention registration ($165 virtual to $1,570 full), donations to the Delta Zeta Foundation (including the $19.02 "1902 Loyalty Society" giving challenge), and merchandise sales through Shop Delta Zeta, the Killarney Wine Club, DZ DeZigns, Herff Jones, Greek Licensing, and Little Words Project. The national philanthropy focus, adopted in 1954, is hearing and speech, executed through long-standing partnerships with the Starkey Hearing Foundation, the American Society for Deaf Children, and SeriousFun Children's Network. Governance is exercised through a National Council, Foundation Board of Trustees, and National Housing Corporation Board; CEO Cindy Winslow Menges is retiring at year-end 2026 after 40+ years, with Michelle Albrecht Smith appointed to succeed her effective January 1, 2027.
