Nephrology Fellowship

Message from the Program Director


neph fellows


The Nephrology Fellowship Program at NYU Winthrop Hospital offers an exceptional training experience characterized by a unique combination of close faculty mentoring, a strong commitment to education and an innovative learning program. Fellows work with a large and diverse patient population with an extraordinary spectrum of clinical disorders related to nephrology and hypertension in the inpatient and outpatient settings. The program has a large outpatient dialysis component and offers in-center hemodialysis, peritoneal dialysis and home hemodialysis. We also have an excellent kidney transplant rotation with NYU Langone Health providing fellows with outstanding training at one of the top centers in the country. In addition, our division has a unique program with NYU Langone Health in which pre-transplant evaluations are done at the divisional offices here at NYU Winthrop, providing patients on Long Island a unique opportunity to get evaluated for transplant. Ongoing research in the division provides fellows the opportunity to participate in clinical, educational, medical informatics and laboratory research covering a wide spectrum of investigative areas. All of this is provided in a supportive environment with an energetic group of faculty who love to teach and facilitate the practice of life-long learning.

We look forward to having the opportunity to meet with you. Please feel free to contact us if you have any questions.
