John A. Guisto, MD, FACEP

Dr. Guisto is originally from Reno, where he grew up enjoying the outdoor opportunities of Northern Nevada, Lake Tahoe and Sierra Nevada Mountains. He left Reno for his undergraduate education at Stanford University, enjoying the breadth of opportunities there, including summers at the Hopkins Marine Biology Research Station in Monterey Bay.

After residency, he took a summer job as a locum tenens physician in an emergency department in Jackson, Wyoming, just for the fun of it. Then, with a couple of friends, he cycled through England and France for a month for the same reason. Upon returning to Tucson, he practiced in various private sector emergency departments in the area. He began filling shifts at Banner – University Medical Center Tucson's Emergency Department and was offered full-time employment. He has been a member of the Department of Emergency Medicine faculty ever since.

Free time interests include cycling, hiking, backpacking, fly fishing and learning various crafts.
