Phi Sigma Gamma (PSG) (ΦΣΓ) is an American men's osteopathic medical fraternity.[1] The fraternity was established in Chicago, Illinois[2] by a merger between two previously existing osteopathic fraternities, Phi Sigma Beta and Phi Omicron Gamma, each of which had three chapters at the time.[1] The date of the merger has been reported both as 1915[1] and as April 1916.[2] A seventh chapter was added to the original six in 1917.[1]

The sole remaining chapter of the fraternity is Zeta Chapter at Philadelphia College of Osteopathic Medicine (PCOM), which is also the only fraternity remaining at PCOM. The headquarters of PSG is located at 270 W. Walnut Lane in Philadelphia, Pennsylvania.[3]

Zeta Chapter history[edit]

The Phi Sigma Gamma fraternity house.

The Zeta Chapter at Philadelphia College of Osteopathic Medicine's headquarters was previously adjacent to the PCOM campus in the 1950s and 1960s on 48th Street in Philadelphia. In the academic year 1976-1977, with the support of Galen S. Young, D.O, Robert L. Meals, D.O., and John W. Becher, D.O, and the undergraduate leadership at the time, Alfred R. D'Angelo, Drake P. DeHart, Robert C. Kasprzak, Barry R. Austin, and Alan R. Maniet, a prospective new chapter house was located in the Germantown section of Philadelphia. The former Phelan Mansion had been converted into a long term care nursing facility. The building did not meet the strict codes required to exist as a nursing facility and the conversion would be too costly. The above mentioned group negotiated to purchase the building then had to hire counsel and petition the Philadelphia Zoning Board for a change in zoning status. The efforts were successful and in the academic year 1977-1978 Phi Sigma Gamma moved into its "new" Chapter House.[citation needed]


The mission of Phi Sigma Gamma is to facilitate the creation and maintenance of professional, as well as social, relationships between medical students and practicing physicians. Membership is open to all male students of Philadelphia College of Osteopathic Medicine.[6]
