Mission Statement and Values

Geisinger Commonwealth is a community-based medical school.

  • Geisinger Commonwealth partners with more than 25 hospitals and healthcare facilities throughout our 17-county region.
  • Geisinger Commonwealth students are engaged in early clinical experiences from the first day of medical school. By shadowing a community physician in his/her office and participating in community health research and quality improvement projects, Geisinger Commonwealth students are engaged. In years one and two, students begin to learn the practice of medicine by building relationships with doctors, healthcare professionals, and patients in the community.
  • Geisinger Commonwealth’s innovative approach to medical education is possible because of the commitment of more than 1200 volunteer clinical faculty members and the patients, families, and residents of the community willing to participate and share their experiences.
  • Students have volunteered more than 26,580 hours to date with nearly 95 organizations in the region.
  • Students have completed more than 165 community health research and quality improvement projects with community organizations in the 17-county region.
  • REACH-HEI program partners with community educational partners to mentor high school students from economically disadvantaged families.

Geisinger Commonwealth offers an innovative curriculum.

  • Innovative ways of training medical students: patient-centered curriculum and experiences; standardized patients; clinical simulations; case-based learning; interprofessional education.
  • Early clinical experiences in years one and two in four regional campuses.
  • The Family Centered Experience Program enables medical students to learn the human aspect of medicine and personal family experiences early in their medical education.
  • Geisinger Commonwealth is among the first United States medical schools to adopt the Longitudinal Integrated Clerkship (LIC) model as the standard clinical experience for the entire medical school class in the third year. The third-year MD program curriculum at Geisinger Commonwealth is an innovative hybrid of inpatient block experiences and a six-month LIC. This hybrid model provides for outstanding continuity of outpatient care with dedicated outpatient faculty, but also allows for intensive blocks of inpatient training in each core discipline.  
  • Geisinger Commonwealth also offers accelerated MBS programs designed to help students strengthen their credentials and candidacy for acceptance into medical and health professional schools.


Geisinger Commonwealth School of Medicine (Geisinger Commonwealth) was established through the grassroots efforts of visionary individuals who foresaw what a community-based medical school would bring to the region and worked to make it a reality. Their goal was to provide more physicians and improved healthcare resources for the people of northeast and north central Pennsylvania. The goal was to create a unique medical education experience that focused on caring for people in their lives and community.

The roots of Geisinger Commonwealth 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 sources, including the Commonwealth of Pennsylvania, Blue Cross of Northeastern Pennsylvania, and other state, federal and private philanthropic sources, the Commonwealth Medical Education Corporation was formed.

The Commonwealth Medical College (TCMC) was incorporated in 2008 and welcomed its first class of Doctor of Medicine (MD) degree students and Master of Biomedical Sciences (MBS) degree students in August 2009.

In April 2011, TCMC opened the 185,000-square-foot Medical Sciences Building in Scranton that houses the academic and research programs. 

The Middle States Commission on Higher Education granted TCMC full accreditation on June 27, 2014 and the Liaison Committee for Medical Education (LCME) granted TCMC full accreditation on July 7, 2014.

TCMC integrated with Geisinger Health System on January 1, 2017, creating Geisinger Commonwealth School of Medicine.

Geisinger Commonwealth has administrative and educational space in Williamsport and in Wilkes-Barre at affiliated hospitals, as well as in Doylestown at the Pennsylvania Biotechnology Center of Bucks County. Geisinger Commonwealth has relationships with more than 25 hospitals in northeastern and north central Pennsylvania which provide learning environments for the students. The College has four regional campuses: North, South, West, and Guthrie, which are integral to the College’s community-based education. Community engagement is part of the fiber of Geisinger Commonwealth. More than 1,200 volunteer clinical faculty members throughout the 17-county region provide students with early clinical experiences and training across the four years of medical education. Families throughout the region are generous in allowing students to follow them so they can appreciate the social context and the impact of illness on the lives of patients. Students are required to pursue research projects in quality improvement and community health.
