Higher education scholars have examined Latino/a student experiences and ethnic identity, yet there is no research describing the ethnic identity development of members of a Latino fraternity at a Hispanic Serving Institution (HSI). The purpose of this phenomenological study was to understand how membership in a Latino fraternity at a HSI enhanced members' ethnic identity development. Utilizing Bronfenbrenner's (2005) bioecological theory of human development as the guiding framework for this study, six themes emerged which enhanced members' ethnic identity development: family, the HSI campus, language, involvement, other Greeks and Greeks affairs policies, and gender. Implications for student affairs and higher education administrators at HSIs and non-HSIs and for Latino parents and families are discussed. In addition, recommendations for future research are explored.
