Epsilon Sigma Alpha International is a service organization for adult women. Established in 1927, ESA is a network of more than 1,000 community based chapters, with coordinating organizations at state and international levels. All service by ESA members is unpaid, with membership fees covering large portions of administrative and chapter expenses. ESA activities on local levels may be jointly organized with men's fraternal organizations, including the Lions Clubs International.

Chapters, both independantly and jointly, conduct fund raising activities for charitable causes. The expenses of handicapped children are a current ESA priority, with funds being raised for St. Jude Children's Research Hospital and Easter Seals, among other charities. In addition, the ESA Foundation has an ongoing Scholarship/Endowment Program and provides grants to individuals involved in charitable service for children and adults.
