Hi, I’m David Armstrong. I’m a professor of surgery and I’m a director of the Southern Arizona Limb Salvage Alliance or SALSA here at the University of Arizona Medical Center. I was born and raised in a little farming town north of Los Angeles called Santa Maria. And I was educated down in Los Angeles and up in San Francisco then I did my residency in beautiful Detroit and my fellowship in beautiful San Antonio. And then I did extra work in the United Kingdom, both in Wales, down in the southwest of England and then up in the northwest and Manchester where I got a PhD. But I am a podiatrist. I’m a toe mechanic, if you will. But my area of specialty and interest is in trying to prevent amputations in folks with diabetes.
