Atlantic Health Overlook Medical Center is a non-profit teaching hospital located in Summit, New Jersey, United States, 20 miles west of New York City. On a hill in the center of the city, the hospital is one of Summit's three largest employers and offers medical services to Summit and surrounding communities in Northern New Jersey.
History Overlook Hospital was founded in 1906 by Dr. William Henry Lawrence, Jr. who purchased land on the "highest point in Summit" overlooking the Baltusrol Valley. There he built a three-story structure which housed an operating room, x-ray facility, and hydraulically powered elevator. This facility, which was privately owned, began with 42 beds and cost approximately $30,000 in total. The hospital established a nursing school in 1912. Further construction increased patient capacity to 148 beds by 1940.
In the 1960s, doctors experimented with new techniques. In one instance, doctors authorized use of alcoholic beverages to delay the onset of contractions of a pregnant woman.
The Valerie Fund Children's Center treats juvenile cancer and rare blood disorders. Established in 1977, it was the first of its kind in New Jersey.
in 1996 Overlook and Morristown Memorial Hospital merged and became Atlantic Health System. The Gerald J. Glasser Brain Tumor Center was established in 1999.
Overlook completed a $197 million expansion program in 2025. In August 2026 management launched a three-year plan to upgrade the surgical facilities, including robotics capabilities; estimated expenditures are $97 million.

Patient billing controversies Overlook was mentioned in a 1991 New York Times article focused on a "financial crisis" in New Jersey healthcare. The Times attributed it to the state legislature's failure to fund a trust which provided financial assistance for low-income patients. Overlook Medical Center, situated in a well-to-do community, added 6% to patients' bills to cover the shortfall. St. Joseph's Hospital and Medical Care Center in Paterson NJ, with more low-income patients, increased patients' bills by 33%. This raised the issue of whether charity patients should be treated equally statewide.
In June 2012 the U.S. Department of Justice announced that AHS Hospital Corp., Atlantic Health System Inc. and Overlook Hospital agreed to pay the United States $9 million to settle allegations that they violated the False Claims Act by allegedly overbilling Medicare. The settlement partially resolved allegations that Overlook overbilled Medicare for patients who were treated on an inpatient basis when they should have been treated as either observation or outpatients, and a False Claims Act suit filed by former employees of Overlook Hospital in U.S. ex rel. Doe et al. v. AHS Hospital Corp., et al., Civ. No. 08-2042 (D.N.J.).
Rail trail at Overlook Area residents have proposed a 7.3-mile pedestrian linear park along the main line of the abandoned Rahway Valley Railroad. The rail trail would run eastbound from the medical center on the edge of downtown Summit and head south along the old railbed through Springfield, Union, Kenilworth and ending at the southwest edge of Roselle Park at the Cranford border. A northern portion of the rail trail on the RVRR main line is under construction as the Summit Park Line, with a footbridge over Morris Avenue installed in October 2022. In parallel, advocates have been pushing for immediate development of the portion south of Route 22, running past the Galloping Hill Golf Course through Kenilworth and Roselle Park. The New Jersey Department of Transportation, which owns the railbed, has been working to clear it in anticipation of possible future trail use.
