Located in Montclair, Hackensack Meridian Health Mountainside Medical Center is proud to continue to provide world-class health care in a community setting. The medical center has successfully transitioned from a stand-alone facility to being part of Hackensack Meridian Health, the most comprehensive and truly integrated network in the state of New Jersey.

Significant capital improvements have been made to the emergency department, women’s services and patient navigation of the medical center as well as upgrades to medical technology, including new state-of-the-art MRI, CT, nuclear medicine and telemetry systems. In addition, Mountainside Medical Group continues to grow with the addition of new physicians in primary care, endocrinology, pulmonology, obstetrics and gynecology and a breast care specialist.
