About Dr. Marc Rybstein

PRIMARY CARE PHYSICIAN: Dr. Marc Rybstein is a Board-Certified Cardiologist, Internist, and Vein specialist in Brooklyn, NY. He was born and raised in Brooklyn and attended New York University for college, where he graduated cum laude with a Bachelor of Science in Chemistry. During college, he served as a teaching assistant for chemistry and organic chemistry courses and worked on research projects related to medical applications of molecules that can bind to and sever DNA. Dr. Rybstein then attended Stony Brook University Medical School and developed an interest in cardiovascular disease, particularly preventive cardiology. His residency at Lenox Hill Hospital in Manhattan involved research on risk factors for ischemic heart disease, resulting in publications in nationally recognized journals. Dr. Rybstein was awarded Resident of the Year during his second year of residency and was elected to the mini-chief program to educate junior residents. *Please note* This is a primary care provider, not a medical specialist - we see patients for a wide range of general health needs, including check-ups, chronic condition management, sick visits, and minor injuries. For concerns that require specialty or surgical care, we can provide an initial evaluation and help coordinate a referral.
