Nephrology Fellowship Program

The Nephrology Fellowship program at UC Davis Medical Center is a 2-year, ACGME-accredited program that combines inpatient consultations at UC Davis Medical Center in Sacramento and at the Sacramento VA Medical Center, outpatient hemodialysis and peritoneal dialysis training, transplantation, and research. Options include elective rotations in pediatric nephrology, in nephropathology, and in interventional nephrology working with an Interventional Radiologist. We take pride in the teaching excellence of our faculty, several of whom have received teaching awards from housestaff and medical students.
