Lambda Psi Delta

Lambda Psi Delta Sorority, Inc. (ΛΨΔ) is a multicultural, community service-based Greek-lettered sorority founded on March 9, 1997.

History
Lambda Psi Delta Sorority, Inc. was founded on March 9, 1997, at Yale University by nine women who were formerly part of a Latina sorority. They decided to leave their former sorority and create an organization whose primary goal was the upliftment and empowerment of women and their communities. They formed Lambda Psi Delta, a multi-ethnic, service-based organization, for women by women and about women. Its motto is "sovereignty to the community."

The founders are referred to as the Nine Black Diamonds. They are: Ericka Ramos Carrasquillo, Irma Beatriz Cordero, Margarita Martis Navarro, Isabel Veguilla, Paula Arputhasamy Ladd, Laura Elaine Gilbert, Karina Tejeda, Marina Lori Franzoni, and Denise J. Pipersburgh.

The sorority incorporated in 1998 in Connecticut. Lambda Psi Delta now has undergraduate chapters in Florida, New Jersey, Connecticut, Texas and Louisiana. It also has two graduate chapters as well as the Connecticut Graduate Association. Although the sorority works primarily in minority communities, its members are from a variety of backgrounds including African, Afro-American, Anglo-American, Belizean, Chilean, Chinese, Colombian, Costa Rican, Dominican, East Indian, El Salvadoran, Ecuadorian, Filipino, Guatemalan, Greek, Haitian, Hungarian, Italian, Iranian, Irish, Jamaican, Korean, Mexican, Pakistani, Palestinian, Polish, Puerto Rican, Russian, Somalian, Scottish, West Indian, Transylvanian, and Vietnamese.

The LILies is the official interest group of Lambda Psi Delta Sorority, Inc. The acronym LILies stands for Ladies Interested in Lambda Psi Delta. The purpose of the LILies group is threefold. It serves to teach interested ladies more about Lambda Psi Delta, encourage service and academic excellence, and to foster a relationship amongst other interested ladies nationwide.
