Bio

James (Jim) Leach, MD, is a Neuroradiologist specializing in Pediatric Neuroradiology at Cincinnati Children's Hospital Medical Center. He grew up in southeastern Ohio and attended Ohio University majoring in Zoology with an emphasis on comparative anatomy. He was inducted into the Alpha Omega Alpha honor society as a third-year student.

After seeing a clinical conference given by Bob Lukin, MD, then chief of Neuroradiology at the University of Cincinnati College of Medicine, he decided on Radiology as a career. He was Chief Resident of Radiology in 1994, and fellow in Neuroradiology from 1995-1997 at the University of Cincinnati.

After serving as a staff neuroradiologist at the UC, Dr. Leach spent five years in private practice at Margaret Mary Community Hospital in Batesville, Indiana, and then returned to UC in 2003. He was program director for the Radiology Residency Program from 2003-2006. Dr. Leach began his full time career at Cincinnati Children's in September 2007, focusing on Pediatric Neuroradiology.
