NSPC Ranked #1 Neurosurgery Practice in NY by Castle Connolly for Third Year in a Row

Castle Connolly: NSPC is Top 10 Neurosurgery Private Practice in U.S. 

(Rockville Centre, NY – January 26, 2026) NSPC Brain & Spine Surgery (NSPC) has been ranked as a Top 10 “private practice for top doctors in neurological surgery in the nation” and the #1 neurosurgery practice group in New York State for the third straight year by Castle Connolly, a New York City research and information company. NSPC was one of the private physician practice groups recognized in an annual national awards survey called the Castle Connolly Accolades.

When Castle Connolly launched the Accolades survey in 2024, the firm’s managing director, Steve Leibforth, said “we introduced Castle Connolly Accolades this year 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. These institutions,” he notes, “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 one of the top neurosurgery practices in the nation and the top ranked neurosurgery physician practice in New York State for the third straight year,” declares Michael H. Brisman M.D., F.A.C.S., the chief executive officer of Rockville Centre, NY-based NSPC. “This achievement,” he asserts, “confirms our practice’s 68-year commitment to patient care and excellence in spine and brain surgery.”

NSPC is Long Island’s largest, private practice neurosurgical group with 11 experienced physicians and seven conveniently located offices on Long Island 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.
