Background

Dr. John P. Gearhart is a professor of pediatrics and urology at the Johns Hopkins School of Medicine, and serves as Director of Pediatric Urology at the Johns Hopkins Children's Center. His clinical and surgical interests focus on the evaluation and treatment of children born with major congenital birth defects, bladder exstrophy, disorders of sexual development and childhood urinary cancers.

Dr. Gearhart received his M.D. from the University of Louisville School of Medicine in 1975. After an internship in surgery and residencies in surgery and urology at the Medical College of Georgia, he completed a fellowship in pediatric urology at Alder Hey Children's Hospital of the University of Liverpool School of Medicine in 1981.

Following two years as a urologist at St. Mary's Hospital in Huntington, West Virginia, he completed a second fellowship in pediatric urology at Johns Hopkins in 1985 and joined the Johns Hopkins faculty thereafter as an associate professor of pediatric urology.

Over the course of his distinguished career, Dr. Gearhart has been lauded as a pioneer in pediatric urology and reconstructive genitourinary surgery.
