Nephrology Fellowship at Mount Sinai West and Mount Sinai Morningside

Since 1977 we have been training fellows to become excellent clinical nephrologists. Our hospitals serve a wide range of patients, and fellows see the full spectrum of diseases that a nephrologist in clinical practice might expect to encounter. Our graduating fellows consistently report that their fellowship prepared them well for practice in Nephrology. We are proud of the fact that over the past 15 years we have had a 100% pass rate on the Nephrology Board Certification Exam. There are a total of four fellows in the training program.

Some of our fellows have gone on to academic careers, some have pursued additional training in Transplantation, Interventional Nephrology and Critical Care and the rest have successfully gone into clinical practice.  Our program consists of 4 Fellows, 6 full-time and 2 part-time staff Clinical Nephrologists. Our fellows benefit from the intimate attention afforded by a small program, and the support of vast resources provided by the Icahn School of Medicine/Mount Sinai Health System.  Despite our clinical focus, fellows have 4 months of research time over the course of the fellowship during which they are expected to develop a research project and at a minimum submit an abstract to one of the national meetings such as the ASN. Fellows are also expected to be involved in a Quality Improvement project during their training.

Our program focuses on training highly skilled physicians to be excellent clinical nephrologists.

Our fellowship accepts candidates from ACGME accredited programs in internal medicine.  Interested applicants should apply through the ERAS system.  Our program is in full compliance with the American Society of Nephrology (ASN) mandate to participate in the NRMP (National Residency Matching Program) and we do not offer “pre-match” positions.  We welcome international graduates and our institution sponsors J1 and H1b visas.  After the match has concluded we are willing to consider exceptional candidates who are not from an ACGME accredited program and other candidates who have decided late to apply to nephrology if any positions are still available.  A successful candidate is someone who is personable and easy to work with like the nephrologists in our division.  We place significant weight on strong letters of recommendation from other clinicians who have gotten to know the candidate one on one.
