In addition to the core faculty listed below, we have a multitude of adjunct faculty at the UAMS-NW Internal Medicine Residency.
Gerry Dean Ezell, M.D.

Interim Program Director
Being a primary care internist gives me the chance to sit and talk with my patients, many of whom have complex and frustrating chronic illnesses, helping them find ways not only to effectively treat their health conditions but also to navigate the equally complicated healthcare system we are a part of. Just being available to listen to patients’ concerns sometimes goes a long way in helping find solutions for their problems.
In his spare time, Dr. Ezell is a volunteer physician for numerous medical mission outreach efforts (local as well as global). He revels in the Arkansas outdoors (hiking, fishing, kayaking), and is a dedicated grandfather to eight grandchildren.
