In addition, Dr. Sturdevant performs both kidney and pancreas transplants, live donor nephrectomy, and general surgical procedures particular to those with end–stage liver (including portal decompression procedures) and kidney disease.

His primary sites of practice will be University of Washington Medical Center – Montlake Campus, Seattle Children’s Hospital, and the VA Puget Sound Health Care System. Born and raised in Sioux City, Iowa, Dr. Sturdevant stayed close to home to complete his bachelor ’s degree in biology, his medical degree, and a one–year student fellowship in surgical pathology at the University of Iowa. His general surgery training was completed at the Carolinas Medical Center in Charlotte and his transplant training started with an abdominal transplant fellowship at the University of Minnesota. He has since held faculty positions in the Divisions of Transplant at The Mount Sinai Hospital in New York City, the University of Pittsburgh, and most recently he spent four years as a Consultant Surgeon in adult and pediatric liver transplantation and hepato–pancreato–biliary surgery at the King Faisal Specialist Hospital & Research Center in Riyadh, Saudi Arabia.
