Our Medical Staff

CNSO Conditions for Spine and Brain SurgeryIn order to provide an accurate diagnosis with the most effective treatment option for “back problems” and brain tumors, CNSO is led by neurosurgeons, orthopedic spine surgeons and reconstructive surgeons.  Neurosurgeons are the experts of the nervous system which includes the brain and the spine. Both neurosurgeons and orthopedic spine surgeons are trained in the biomechanical bone structure of the spine called the vertebral bones.  CNSO surgeons are trained in neurosurgery, orthopedic spine, plastics, breast reconstruction, and hand surgery. There is also a team of medical doctors specializing in rehabilitation, pain management, neurology, sports medicine, and physical therapy. Under the care of our award-winning medical staff, Northern NJ patients can have the confidence that their medical condition will be handled with consideration for their comfort and long-term well-being as well as technical excellence.
