Our Team

Rochester General nephrologists, physician assistants, nurse practitioners, nurses, dietitians and social workers treat all types of kidney disorders, both common and rare. Our record of providing the highest standard of care has earned the trust and loyalty of our patients and made our Nephrology Unit one of the region’s largest and most respected.

Every nephrologist is board certified in internal medicine as well as nephrology. Many have further education and associated credentials. Our nephrologists assist in the training of Rochester General internal medicine students as well as medical students from various locations, including the University of Rochester.
