Congratulations are also in order for Dr. Bradford, who was chosen for the 'Texas Monthly' SuperDoctor 'Rising Star' listing of physicians in their July 2014 issue. He was the only Internal Medicine physician in our region chosen for this honor.

Dr. Bradford was born in Tougaloo, MS and graduated high school from the Mississippi School for Mathematics and Science in Columbus, MS in 1992. After graduating cum laude with a BS from Tougaloo College in 1996, he spent two years conducting research and publishing at the National Institutes of Health in Rockville, Maryland. Dr. Bradford subsequently attended the Virginia Commonwealth University / Medical College of Virginia School of Medicine in Richmond, Virginia. After graduating in 2002, he and his wife moved to Amarillo where he completed his Internal Medicine Residency at Texas Tech University Health Sciences Center in 2005.

Because Dr. Bradford has an aggressive desire to serve patients and assist them in functional health, he specializes in Primary Care Internal Medicine for adult men and women.
