Spine Associates of NYC Expands Specialty Surgery Practice to New Jersey

The expansion brings a team of high-profile surgeons—including Sean McCance, Baron Lonner, David Matusz, John Caridi, and Peter Frelinghuysen—to Morris County. The practice focuses on a wide spectrum of spinal health, ranging from common ailments like herniated discs and stenosis to complex scoliosis and revision surgeries. Dr. McCance, who serves as the founder and director, emphasized that the New Jersey office is an extension of the Manhattan practice rather than a separate satellite entity. This ensures that patients receive identical standards of care and personalized follow-up protocols without the necessity of commuting into New York.

Each surgeon at the new location brings distinct expertise to the region. Dr. Lonner specializes in complex spinal deformity, while Dr. Caridi offers a neurosurgical perspective on advanced reconstruction. Dr. Matusz focuses on degenerative conditions and disc replacement, and Dr. Frelinghuysen provides a hands-on approach to cervical and lumbar treatments. For patients who have historically traveled to the Upper East Side for specialized spine care, the Cedar Knolls office serves as a more accessible alternative, maintaining the same clinical philosophy that prioritizes non-surgical intervention whenever possible.
