Hackensack University Medical Center and its parent company are merging with Meridian Health and its six hospitals in Ocean and Monmouth counties to create the state's largest hospital network. The new organization, to be called Hackensack Meridian Health, will employ 23,400 people and have more than $3.4 billion in revenues, eclipsing Barnabas Health, currently the state's largest health care system. The "combined organization would serve a much broader geography, expanding access to services and developing a vast array of new non-hospital services to conveniently serve area communities," Robert C. Garrett, president and CEO of Hackensack University Health Network, said. The plan to merge was announced Thursday.
