Dr. Kamal Nayyar

Physician – Internal Medicine & Nephrology In Smithtown & Bohemia, NY

New York Comprehensive Medical Care

My journey into medicine began first with an interest in science. I obtained my Bachelor of Science in Biochemistry from Stony Brook University. It was there that I built the foundation to achieve better insight into mechanisms underlying the disease processes I would study in medical school. After achieving my Doctor of Medicine degree, I left my native New York to pursue Internal Medicine training at the Morehouse School of Medicine in the greater Atlanta area. I continued to hone my skills as both a physician and an educator, serving as a chief medical resident and also an instructor in the department of internal medicine. The study of kidney disease provided the platform upon which to combine a passion for physiology with the desire to help my community. As such, I returned to New York for Nephrology fellowship at NYU Winthrop Hospital.
