The Nephrology Fellowship program at the UC Davis School of Medicine is a 2-year, ACGME-accredited program that covers the spectrum of nephrology clinical practice. The program sites include the UC Davis Medical Center located in Sacramento, the VA Medical Center located at Mather Field, as well as numerous outpatient dialysis clinics scattered around the city. The program provides excellent teaching and training with unique experiences in home dialysis modalities and interventional nephrology. We take pride in the teaching excellence of our faculty, several of whom have received teaching awards from residents and medical students. Additionally, UC Davis has one of the busiest renal transplant programs in the country, and the Nephrology Division, highly ranked in the US News and World Report, is very active in clinical and basic science research.
