my reasons:
I was in AWE of the history and legacy of Sigma
the women I encountered who were my sisters even before they were my sorors- esp Soror Degraffenreid, she was the president of the chapter and a senior when I was a freshman (she actually celebrates her 6 year Sigmaversary today
)
the creativity and tenacity of the chapter on my campus
the national and local service initiatives which the chapter implemented and represented
the diversity: the fact that the sisterhood was comprised of women of all backgrounds, colors, shapes, interests, etc.
the fact that the sorority was founded and focuses on education and serving our communities
the ability to take on the Name and traditions of what I call Tribe Sigma
the way Sigma Gamma Rho women carry themselves
and make a mark
