Dr. Rybstein was born and raised on Long Island. He attended New York University for college during which he was in the honors program and graduated cum laude with a Bachelors of Science in Chemistry. During college he served as a teaching assistant for several courses including chemistry and organic chemistry. He also worked on various research projects in chemistry focusing on the potential medical applications of molecules which can bind to and sever DNA in specific locations. He also published several articles in journals including the Journal of Inorganic Chemistry.
After college, Dr. Rybstein returned to his Long Island roots and attended Stony Brook University Medical School. During medical school he developed an interest in cardiovascular disease particularly with an eye towards preventive cardiology. Following medical school, during residency in Internal Medicine at Lenox Hill Hospital in Manhattan, Dr. Rybstein furthered his interest in preventive cardiovascular disease by participating in several research projects involved in further delineating specific risk factors for ischemic heart disease. This research resulted in several publications in nationally recognized journals, such as CHEST Journal, the official publication of the American College of Chest Physicians.

St. Vincent’s closed due to financial issues prior to the beginning of his fellowship and Dr. Rybstein then served as an Internal Medicine attending for two years in the New York area prior to beginning a cardiovascular fellowship at Winthrop University Hospital, a clinical campus of Stony Brook University Hospital, on Long Island. During fellowship, Dr. Rybstein cared for patients having the spectrum of cardiovascular issues. These included but were not limited to ischemic heart disease, non-ischemic cardiomyopathies, valvular heart disease, arrhythmias, hypertension and lipid management. During fellowship Dr. Rybstein completed his certification exams in nuclear cardiology as well as the physicians vascular interpretation exam. Besides for his interests in the full range of cardiovascular diseases, Dr. Rybstein also specializes in the diagnosis and treatment of venous diseases. Specifically, he specializes in treating the full gamut of venous diseases including spider veins and chronic venous insufficiency. He is proficient at sclerotherapy, foam sclerotherapy, radiofrequency ablation, laser ablation and vein stripping.
