Hermandad de Sigma Iota Alpha, Inc. (SIA) was founded on September 29, 1990 at four universities in the state of New York by a diverse group of women with the goal of creating an organization that would help their communities, unite women, and uphold a distinct set of goals. Its dedication to scholarship, service, and professional development within the Latino community has grown beyond New York, with over 40 chapters & colonies nationwide. 

SIA is more than a sorority; we are a family and network of professional, strong, and dedicated women leaders.  We are also a 501(c)7 tax exempt organization and we work in conjunction with the Solidaridad Inspiración Amistad Community Foundation, Inc., a 501(c)3 community foundation committed to scholarship, service, and professional development within Latino communities nationally.
