History

Thirteen Latina women established Alpha Pi Sigma on March 10, 1990, at San Diego State University.^[5][3] They saw the need to unite and support Latina women on university campuses.^[6]

The sorority's founders established six purposes that define the organization. The chapters carry out these purposes, including academic excellence, leadership development, cultural awareness, unity and friendship, empowerment, and community service.^[1][2][3] However, academic excellence is the sorority's primary value, along with community service.^[3]

The sorority is a member of the National Association of Latino Fraternal Organizations (NALFO) and holds a strict anti-hazing policy.^[7]

Symbols

The sorority's motto is Amigas Para Siempre. Its colors are baby pink and royal purple. Its symbol is the infinity sign. Its flower is the white calla lily.

Philanthropy

Both active sisters and alumnae are encouraged to raise funds to support the sorority's national philanthropy.^[8] Chapters also select their philanthropies and volunteer in the Latino community.^[3] Some examples of the Alpha Pi Sigma efforts are American Cancer Society, autism awareness, lunch distribution, heart disease awareness, a Tijuana-based orphanage, and Relay for Life.^[1][9][3]
