NSPC Brain & Spine Surgery (NSPC) has been ranked as the #1 neurosurgical practice in New York State for the second consecutive year by Castle Connolly, a New York City research and information company. NSPC was one of the physician practice groups recognized in a national awards survey called the 2025 Castle Connolly Accolades.
Last year, in the same survey, Castle Connolly ranked NSPC among the top five practice groups in the U.S. and as the #1 neurosurgery practice in New York.
When Castle Connoly introduced its Accolades survey in 2024, Steve Leibforth, the firm’s managing director, said it was created “to recognize multiple institutions – ranging from health systems providing comprehensive care to an entire region, to community-based physician practices excelling in specific and specialized care. The institutions all employ exceptional physicians who have been recognized as Castle Connolly Top Doctors, ensuring the highest quality care for their patients.”
“We are honored to have been ranked, again, by Castle Connolly as the top physician practice in New York,” declares Michael H. Brisman M.D., F.A.C.S., the CEO of Rockville Centre, NY-based NSPC. “This achievement,” he asserts, “confirms our group’s 67-year commitment to personalized patient care and excellence in spine and brain surgery.” NSPC is Long Island’s largest, independent neurosurgical group with 12 experienced neurosurgeons and seven conveniently located offices on Long Island offices and in Manhattan.
The NSPC Castle Connolly “Top Doctors” are: Jonathan L. Brisman, M.D. (Cerebrovascular, Spine and Brain Surgery), Benjamin R. Cohen, M.D (Spine Surgery), Vladimir Y. Dadashev, M.D. (Spine Surgery), Zachariah M. George, M.D (Spine Surgery), Yusef Imani, M.D. (Spine Surgery), Stephen T. Onesti, M.D. (Spine Surgery), and Sachin N. Shah, M.D. (Spine Surgery).
For decades, Castle Connolly has been conducting a peer-review survey to select the region’s top doctors based on the theory that medical professionals are best qualified to assess the qualifications of other practitioners. Licensed physicians vote online for those doctors they consider outstanding. A Castle Connolly doctor-led research team then counts the nominations and vets the nominee pool with the aid of several screens, including confirming board certifications and investigating disciplinary histories. In 2020, Castle Connolly was acquired by the Everyday Health Group, a division of J2 Global Inc.
