Background

Dr. C. John Sperati is an Associate Professor of Medicine at the Johns Hopkins University School of Medicine. His areas of clinical expertise include renal medicine. 

Dr. Sperati is Director of the Nephrology Fellowship Training Program and serves as the Firm Faculty Leader of the Barker Firm.  In addition, he co-directs the Johns Hopkins Osler Learning Initiative which brings the principles of medical residency training to executive education worldwide.

He obtained his medical degree from The Pennsylvania State University College of Medicine and a Master in Health Science from the Johns Hopkins Bloomberg School of Public Health. He completed an internship and residency in Internal Medicine at the Johns Hopkins Hospital, followed by a year as an Assistant Chief of Service (chief resident). He subsequently pursued subspecialty training in nephrology at the Johns Hopkins Hospital and joined the faculty in the Division of Nephrology. He is board certified in Internal Medicine and Nephrology.

Dr. Sperati’s clinical interests are in thrombotic microangiopathy including atypical hemolytic uremic syndrome (aHUS), complement mediated kidney diseases including C3 glomerulopathy, secondary and resistant hypertension (fibromuscular dysplasia, atherosclerotic renal arterial disease, hyperaldosteronism, and genetic hypertensive syndromes), glomerulonephritis (e.g., IgA nephropathy, MPGN), and nephrotic syndromes (e.g., FSGS, membranous, minimal change, amyloidosis, and others).  He is the site principal investigator for several clinical studies, serves on editorial boards, and is a member of the National Kidney Foundation Education Committee as well as the Nephrology Knowledge Check-in Task Force of the American Board of Internal Medicine.  His clinical expertise has been recognized by induction into the Miller Coulson Academy of Clinical Excellence.

This provider is registered with the Florida Department of Health to perform telehealth services for patients in Florida.
