The Σ Difference


All Sororities were founded to aid their communities and provide opportunities of sisterhood. Yet each has something different to offer.


The Sigma difference is that we are interested in developing each member as a person so that collectively, we are women of substance that are dedicated to community service. In mathematics, Σ represents a sum total. Likewise, our sisterhood is interested in each sister as a total person on a spiritual, mental and emotional level. Sigma helps each member to develop and reach their full potential which allows our sisterhood to be a collective group of women that are strong, focused, and committed.


The Sigma difference is that we are interested in who you are, not what you own or who you know.


The Sigma difference is that we care. We care about our members, our communities and our youth that we are training to be leaders.


Sigma is different because with our motto of “Greater Service, Greater Progress”, we make a difference.
