Geisinger Commonwealth School of Medicine (GCSOM) is a private medical school associated with the Geisinger Health System in northeastern and north central Pennsylvania. GCSOM offers a community-based model of medical education with six regional campuses - North (Scranton, PA), South (Wilkes-Barre, PA), Central (Danville, PA), West (Lewistown, PA), Atlanticare (Atlantic City, NJ), and Guthrie (Sayre, PA). It offers a Doctor of Medicine (MD) Program and a Master of Biomedical Sciences (MBS) Program. History The foundation of GCSOM, formerly known as The Commonwealth Medical College (TCMC), began with the establishment of the Northeastern Pennsylvania Medical Education Development Consortium (MEDC) in 2004. The consortium included business, medical, community, and government representatives. After acquiring funding from the Commonwealth of Pennsylvania, Blue Cross of Northeastern Pennsylvania, and other state, federal and private philanthropic sources, the Commonwealth Medical Education Corporation was formed. In the spring of 2007, Robert M. D’Alessandri began his tenure as president and founding dean. Commonwealth was awarded degree-granting authority by the Commonwealth of Pennsylvania in 2008 and received preliminary accreditation by the Liaison Committee on Medical Education (LCME) in 2008. D'Alessandri resigned from his position as dean and president in April 2011. In June 2011, the LCME placed GCSOM on probation due to financial stability concerns. Provisional accreditation was granted in 2012, with full accreditation granted in June 2014. In June 2014, GCSOM was also granted full accreditation by the Middle States Commission on Higher Education (MSCHE). GCSOM accepted its first class of medical and master's students in 2009. GCSOM graduated its first MD and fourth MBS classes in May 2013. On September 28, 2016, Geisinger Health System announced it had acquired the Commonwealth Medical College. The acquisition integrated aspects of the health system, such as residency training programs, into TCMC, and also introduced new Master's programs. Additionally, TCMC was renamed Geisinger Commonwealth School of Medicine. On September 2021, Geisinger announced that Julie Byerley, M.D., M.P.H., will serve as the new president and dean of the Geisinger Commonwealth School of Medicine, executive vice president and chief academic officer, effective January 1, 2022.
