Ramin Rak, M.D., F.A.A.N.S., F.C.N.S., is a board certified neurosurgeon who performs complex neurosurgery. He has extensive experience in performing awake craniotomies. Dr. Rak specializes in the treatment of neurological tumors and cerebrovascular and skull base diseases. He uses stereotactic radiosurgery, such as Cyberknife®, as well as complex and minimally invasive spinal procedures. Dr. Rak is an expert in micro-neurosurgical techniques which he utilizes to perform most of his surgeries.
Dr. Rak received his undergraduate degree with high honors in Medical Basic Sciences and his medical degree from the Free University of Brussels, Brussels, Belgium. He then completed an externship followed by Internship and another year of General Surgery residency in the department of surgery at Washington Hospital Center, Washington, D.C. Dr. Rak was a clinical neurosurgery fellow, NIH/NINDS/Surgical Neurology Branch, Bethesda, MD; then a neurosurgery resident at the department of neurosurgery, George Washington University, Washington, D.C. He then joined Dr. Sekhar at the Mid-Atlantic Brain and Spine Institute in Annandale, VA and University of Maryland in Baltimore, MD for a microneurosurgery clinical and research fellowship. He established the “Brain and Spinal Cord Foundation” with Dr. Sekhar in Northern Virginia.
Dr. Rak became a clinical neurosurgery fellow, cerebrovascular and skull base surgery under Dr. Sekhar at North Shore-LIJ, then chief neurosurgery resident, department of neurosurgery, University of New Mexico, Albuquerque, NM, where he also taught a neurosurgery lecture series.
For more than 30 years, Dr. Rak has conducted basic neuroscience and clinical research in a variety of neurologicial conditions, including reperfusion injuries after treatment of stroke, micro-neurosurgical techniques and outcomes of difficult skull base and cerebrovascular diseases and usage of adult Olfactory Ensheathing Glial and Schwann Cells (OEC) in spinal cord injuries. He has published several dozen articles and book chapters in the main neurosurgical journals and book atlases.
Dr. Rak has presented at more than twenty professional meetings on topics such as Minimizing Reperfusion injuries after treatment of stroke, Neuronavigation in Skull Base Surgery, Reconstruction Options for the Complex Posterior Fossa and Middle Cerebral Artery Aneurysms, and Functional Recovery after Spinal Cord Injuries/Optic Nerve Injuries/Brain Stem Injuries in Patients Transplanted with Olfactory Ensheathing Glial and Schwann Cells (OEC.)
The Society for Brain Mapping and Therapeutics (SBMT) appointed Dr. Rak to its Board of Directors in 2013. His committee assignment at SBMT will include a leadership position for the membership committee. He will also be involved in organizing 2018/19 World Brain Mapping in NYC. Dr. Rak is a member of the (AANS) American Association of Neurological Surgeons and the (CNS) Congress of Neurological Surgeons. Dr. Rak is currently the incoming president of the (SCMS) Suffolk County Medical Society and Suffolk Academy of Medicine and the past president of the (NYSNS) New York State Neurosurgical Society.
Dr. Rak is the Chief of Neurosurgery at St. Catherine of Siena Medical Center, the Director of Neurosurgical Trauma Services at Mount Sinai South Nassau, as well as the Director of Brain and Spine Tumor Program at Mount Sinai South Nassau/NSPC. He was recently appointed to New York State Department of Health’s Spinal Cord Injury Research Board (SCIRB), whose mission is to support neurological spinal cord injury scientific research projects from leading researchers within New York State to find a cure for spinal cord injuries. In 2026, Dr. Rak was elected as Vice President of the Medical Society of the State of New York (MSSNY), where he will help guide MSSNY’s strategic priorities at a time when physicians continue to face significant administrative, financial, and workforce challenges. His experience, leadership, and dedication to the profession will play a critical role in strengthening MSSNY’s advocacy on behalf of physicians and the patients they serve.
Dr. Rak speaks fluent Persian and French.

NSPC Neurosurgeon, Dr. Jonathan Brisman, Addresses Billy Joel’s Brain Disorder Diagnosis
(May 27, 2025 – Rockville Centre, NY) According to many published reports, singer/songwriter and Hicksville native Billy Joel, 76, has cancelled all his upcoming concert appearances due to a recent diagnosis of Normal Pressure Hydrocephalus (NPH). A relatively unknown condition, NPH occurs when there’s a gradual buildup of cerebrospinal fluid (CSF) in a person’s skull which presses on their brain and disrupts such functions as memory and movement.
Board-certified, Long Island neurosurgeon Jonathan Brisman M.D., an attending neurosurgeon and senior partner at NSPC Brain & Spine Surgery (NSPC), points out that “NPH is often difficult to diagnose because its symptoms are similar to other age-related conditions, including dementia, and treatment rarely involves medication.”
Dr. Brisman has successfully treated many people with NPH and he says Joel’s condition could be reversible. “Unlike other dementia-like diseases, when diagnosed early, NPH can usually be addressed by surgically implanting a programmable shunt that controls the flow of CSF and prevents the fluid from building up.” Dr. Brisman has performed this procedure at several local hospitals and says patients are usually discharged the day after surgery.
According to the Cleveland Clinic, NPH “affects about 0.2% of people between the ages of 70 and 80, and about 5.9% of people over 80.” NPH is most common in people over 65 years of age, and the condition becomes more common as people age.
A Nassau resident, Jonathan Brisman M.D., F.A.C.S., completed his neurosurgical training at Massachusetts General Hospital and has been in practice on Long Island since 2009. He sees patients at offices in Lake Success, Rockville Centre, and Manhattan.
