Our Sorority is dedicated to educating the community about Latino culture - our history, struggles and endeavors. We hope to educate and unify not only the many diverse Latino cultures but other ethnic groups as well. SIA strives to provide a sense of pride for our heritage and in doing so hopes to abolish ignorance, prejudice and racism in the community at large.

At the moment SIA is composed of chapters in the New York State area as well as in the states of Illinois, Pennsylvania, and Massachusetts and is considered national. The chapters are composed of undergraduate, graduate and professional women.

Our Sorority takes pride in becoming involved in the community. We strive to serve the needy by participating in local, national, and international causes.

Our goals are: first, to constantly strive towards increased awareness of the Latino culture, as well as other cultures, to the community at large. Second, to promote sisterhood and leadership among ourselves. Third, to serve as models of excellence in academics and achievements among women. We encourage all women, whether they are in the Hermandad or not, to promote a diverse cultural and social environment. Our endeavor is to work as sisters united in these common goals; however, we value personal identity and individualism highly. Through the bonds of sisterhood, we develop leadership, scholarship, sportsmanship and friendship.
