We are proud to announce that our three senior neurologists have been named to the prestigious Castle Connolly Top Doctors list for 2026, and featured in New York Magazine. Dr. Sadiq, Dr. Williams, and Dr. Stark have each earned this recognition, reflecting the exceptional care that defines IMSMP.
Since 1991, the Castle Connolly Top Doctors list has been a trusted source for identifying top physicians through a rigorous nomination and research process. Doctors are selected based on nominations from their peers, and they cannot pay to be included. As a result, only 7% of practicing doctors in the United States make the list and each one is guaranteed to provide outstanding care.
As the founder and director of IMSMP and the Tisch Multiple Sclerosis Research Center of New York, Dr. Sadiq has appeared in New York Magazine's Top Doctors list since 1996.
Dr. Sadiq’s dual commitment to cutting-edge research and compassionate patient care has positioned him as an internationally recognized leader in multiple sclerosis research and treatment.
"Being recognized by Castle Connolly over the years is deeply humbling," Dr. Sadiq reflects. "But the true honor is the opportunity to serve our patients and advance the science that will one day cure MS.”
Dr. Williams has earned Castle Connolly Top Doctor recognition for ten consecutive years. His patient-centered approach has come to define his career, and he has become a cornerstone of our clinical team.
"This recognition belongs as much to our patients as it does to me," Dr. Williams shares. "They trust us with their care, share their lives with us, and inspire us to be better doctors every single day. At IMSMP, advanced neurology meets genuine human connection. That's what makes this work so meaningful."
Dr. Stark has been recognized as a Castle Connolly Top Doctor for eight years and was named a Top LGBTQ+ Doctor in 2024 and 2025. Dr. Stark also directs our fellowship program for neurology residents seeking specialization in MS and neuroimmunology.
"My clinical philosophy has always been rooted in education and empowerment," Dr. Stark explains. "This recognition tells me that our approach at IMSMP—taking time with patients, explaining the science, and making decisions together—is working.”
Having all three of our senior neurologists simultaneously recognized as Castle Connolly Top Doctors validates our practice-wide commitment to excellence, innovation, and patient-centered care.
As we celebrate this achievement, we remain focused on our core mission: providing world-class MS care that is personalized for every patient. These awards remind us why we do this work, and inspire us to continue pushing the boundaries of what is possible in MS.
Congratulations to Drs. Sadiq, Williams, and Stark!
