- I specialize in adult and pediatric kidney and liver transplant surgery. I received my medical degree from UT Health San Antonio. I completed his residency and transplant fellowship at Wilford Hall Medical Center in San Antonio, Texas, and Massachusetts General Hospital. I specialize in adult and pediatric kidney and liver transplant surgery and have served with the United States Air Force overseas. I have also contributed to many notable publications in my field.
