Dr. Long is an Assistant Professor of Urology in Surgery at Penn and an attending urologist at the Children’s Hospital of Philadelphia (CHOP).  He earned his M.D. degree from Rutgers New Jersey Medical School. He completed his internship in general surgery followed by a residency in urology at Temple University Hospital in Philadelphia before coming to CHOP for his fellowship in Pediatric Urology in 2012. Dr. Long was awarded the prestigious Urologic Care Foundation Research Scholar Award.

Dr. Long’s practice will encompass all aspects of pediatric urology and is committed to the delivery of compassionate care to all children in need to urologic care.  In line with his research investigating the neurologic and physiologic basis of voiding and bladder outlet obstruction, Dr. Long will be involved in caring for patients with neuropathic and non-neuropathic bladder dysfunction. Dr. Long’s other special clinical interests include complex reconstruction, including hypospadias, minimally invasive and robotic-assisted techniques for genitourinary reconstruction, pediatric stone disease, and pediatric urologic oncology.
