Hackensack University Medical Center Founded in 1888 with just 12 beds, HackensackUMC was Bergen County's first hospital. As we continue to grow and flourish, this nonprofit, teaching and research hospital has grown to become the largest provider of inpatient and outpatient services in New Jersey. Not only have we added 763 more beds to our facilities, were now Bergen Countys hub of healthcare for the Northern New Jersey and New York metropolitan areas. Hackensack University Medical Center, part of the Hackensack University Health Network, is truly an extraordinary place bringing together exceptional patient care and medical innovation. This powerful combination enables us to take medicine further than ever before, to push beyond traditional thinking and provide patients with amazing possibilities.
