Theta Delta Sigma was established at the State University of New York, Buffalo on April 15, 2001 and recognized by the university as an official and organizing group on campus the same semester.

These founding siblings - Jamel Catoe, Ritchie Chavez, Kimberly Cheng, Gilbert Chu, Yvonne Gong, Michael Liu, Cecilia Mejia, Brian Philips, Naudeya Richards, Melissa Tang, Joey Tsao, Iris Wangpataravanich, Jim Wong, and Judy Wong came together from different cultural backgrounds as one.

These 14 extraordinary men and women united with a single vision, a rare vision, of uniting men and women of all cultural backgrounds in bonds of 'siblinghood' and providing others an opportunity to use their pride in their heritage, open mind to celebrate diversity and multiculturalism and to become leaders in society.

On March 23, 2003, Theta Delta Sigma was recognized under the laws of the State of New York as a non-profit organization as Theta Delta Sigma Society, Incorporated.

Today, Theta Delta Sigma has grown past the boundaries of the University at Buffalo and Western New York and we have formed a union amongst members of different ethnicities, religions, and cultures becoming a culturally revolutionary and unprecedented society.

We, the siblings of Theta Delta Sigma Society, will uphold the ideals of our founders and seek to establish and perpetuate siblinghood and the utmost unity while increasing minority awareness, diversity, and multiculturalism.

Thirteen of our 14 founders.
