Bradley Walker, M.D., MPH

I’m Brad Walker, 65 years old, and hoping to become Board Eligible in the specialty of Medical Informatics (ABPM) via the Clinical Informatics Fellowship at UAMS. 

I’ve seen around 200,000 patients in urgent, primary, and occmed encounters; been the medical director of an FQHC; published award-winning studies; been the elected head of a physician’s union (120 members at peak) for 20 years in Las Vegas, Nevada (Clark County, University Medical Center); and been the principal founder of a humanitarian foundation working in childhood starvation and malnutrition in 21 countries/12 languages over 15+ years with at peak about 15,000 enrolled children under six years of age. 

I have six kids, three of whom followed me into medicine, all grown up now, and six grandkids. I love working in clinical informatics and hope/plan to continue to do in the future as able.
