In January 1964, a group of women wanting unity at the university formed an organization called TRI SIS. Service, integrity and sociability were symbolized in their name and their motto "true to one another." In 1967, they became Epsilon Lambda with 96 charter members, including 57 collegians, 34 of the alumnae pledge group, four alumnae initiates and one honorary initiate. The chapter rented a townhouse for years and moved to a new university owned building in 2003. After a chapter decision in the late 1990s, Epsilon Lambda became the first sorority on campus to be alcohol-free. They are a multiple recipient of the "Most Outstanding Sorority on Campus" award. Former chapter advisor and Province Director Jane Siling was the first woman Deputy Chief of the Tampa Police Department.
