Nephrology Fellows | NYU Winthrop Hospital

Welcome to the website for the Nephrology Fellowship Program at NYU Winthrop Hospital. We offer an exceptional training experience in nephrology in a setting characterized by a unique combination of close faculty mentoring, a strong commitment to education with an innovative learning program, and 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 also has a large outpatient dialysis program and offers in-center hemodialysis, peritoneal dialysis and home hemodialysis. We also have an excellent Kidney Transplant rotation with Columbia University Medical Center providing fellows with outstanding training in kidney transplantation at one of the top centers in the country. In addition, our division has a unique program with Columbia 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 hope you enjoy visiting our website and learning about our fellowship program and we look forward to having the opportunity to meet with you. Please feel free to contact us.
