Always maintaining a patient-centered focus, Atlantic Health System has evolved to meet the expanding needs of the 11 counties and 4.9 million people it serves. Initially including the now Morristown Medical CenterOverlook Medical Center and Goryeb Children’s Hospital, Atlantic Health System grew to include Newton Medical Center (2011), Chilton Medical Center (2014) and Hackettstown Medical Center (2016), along with the new Atlantic Rehabilitation Institute (2019), new partnership with CentraState Health System (2021), and longstanding alliance with Hunterdon Healthcare (2014).
