About Us

Columbia University Irving Medical Center's Office of Government & Community Affairs (GCA) represents the interests of the medical center before the federal, state, and city governments. This office also develops and implements programs with the communities surrounding Columbia University Irving Medical Center, and serves as the primary liaison between the medical center and the external community.

GCA coordinates information on services and programs available at the medical center campus. The office responds to and engages community stakeholders, local residents and community-based providers as they seek to learn more about the various medical center programs, services, events, and activities. We work with various elected officials, medical associations, and other organizations to advocate and educate policymakers on areas of interest of our faculty and staff. We also work with our affiliates NewYork-Presbyterian and New York State Psychiatric Institute, as well as our colleagues at Columbia's Morningside campus Office of Government & Community Affairs, to further our mission.

If you have any need or desire to work with elected officials or community-based organizations, I strongly encourage you to contact us to see if we may be of assistance.
