Delta Sigma Pi is an American professional business fraternity for men and women. It was founded in 1907 at the School of Commerce, Accounts and Finance of New York University in New York City, New York. The fraternity has both collegiate and alumni chapters. It refers to chapters under development, traditionally known as colonies, as startup groups.
Collegiate chapter designations are assigned using the letters of the Greek alphabet in the following order: single letters in order from Alpha to Omega, shifting to double letters from Alpha Beta to Alpha Omega, Beta Gamma to Beta Omega, Delta Gamma to Delta Omega, etc. Once the chapter names reached Omega Psi, the system changes to run in reverse from Omega Psi to Omega Alpha and then to the previously skipped Psi Chi to Psi Alpha, Chi Phi to Chi Alpha, etc. Doubled or repetitive letters, such as Alpha Alpha, are not used for chapter names.
