Trailblazers in Black History: Sigma Pi Phi

Sigma Pi Phi (ΣΠΦ) is the first successful and oldest African-American Greek-lettered organization. 

Sigma Pi Phi was founded in Philadelphia, Pennsylvania, on May 15, 1904. The fraternity quickly established chapters (referred to as "member boulés") in Chicago, IL and then Baltimore, MD.

The founders included two doctors, a dentist and a physician. When Sigma Pi Phi was founded, Black professionals were not offered participation in the professional and cultural associations organized by the white community. 

Sigma Pi Phi has over 5,000 members and 126 chapters throughout the United States and the West Indies.
