Continuously moving forward

Never content with the status quo, we continue to add services, staff, programs and technology to benefit our patients and our communities. From our state-of-the-art emergency center with its Fast Track program to our holistic mind-body women's program to our comprehensive cancer center and a weight-loss surgery program recognized nationally as a Center of Excellence, Mountainside Medical Center is the right choice in the greater Montclair area.

In 1891, the beginning of a great tradition

Margaret Jane Merewether Power was a preacher’s daughter who came from England to Montclair in 1874 with her husband. One summer day in 1890 she encountered a child who had fallen from a third-story window. Upset that there was no nearby healthcare facility where the child could be helped, she called on other women in her social circle to find a solution – marking the birth of Mountainside Medical Center. By 1891, a three-story cottage belonging to widow Eliza Sheridan had been purchased. Dr. John J.H. Love was named the first President of the Medical and Surgical Staff, and Mountainside Medical Center officially began its mission of “caring for, curing and nurturing the sick and injured.” Today, nearly 130 years later, Mountainside Medical Center is still carrying out that mission. With 365 beds and 820,000 square feet in total, Mountainside Medical Center has come a long way. But some things never change. The compassion and commitment to the community felt by Mrs. Power continues to this day.
