JD Foster

I’m a Pennsylvania native and went to the University of Pennsylvania for veterinary school.  After working for a year in private practice, I completed a rotating internship at the VCA Norwalk/Shoreline referral hospitals in Connecticut. Thereafter I completed an internal medicine residency at the University of Wisconsin.

Upon becoming a board certified internal medicine specialist, I returned to the University of Pennsylvania as faculty, where I spent 4 years running the hemodialysis and blood purification service. I have completed a long-distance nephrology and hemodialysis fellowship under the training of Dr. Larry Cowgill at the University of California, Davis. I joined the FHA team in September of 2016. In 2018, I became President of the American Society of Veterinary Nephrology and Urology.
