About
Dr. Jana McKenzie earned her bachelor's degree in pre-med and science with a psychology major from the University of Michigan, finishing in the top 5% of her class. While there, she contributed to groundbreaking research on extracorporeal membrane oxygenation, known as ECMO. She then earned her MD from the University of Cincinnati College of Medicine, graduating in the top 10% of her class. She completed her residency in Internal Medicine at the University of Cincinnati Medical Center in 1998 and also trained at the University of Alabama Medical Center. Dr. McKenzie holds board certification in Internal Medicine and membership in Alpha Omega Alpha, the national medical honor society.
She originally set her sights on interventional cardiology, but her internship and residency pulled her firmly toward internal medicine. Over a career spanning rural Florida, solo practice in Georgia, and charitable clinic work in Jupiter, she developed deep expertise in complex and difficult-to-diagnose conditions. Her son's nickname for her, the Medical Detective, reflects her reputation for taking on cases that stump other physicians. Her clinical focus covers diabetes, heart failure, arrhythmias, autoimmune diseases, pulmonary conditions, thyroid disease, psychiatric conditions, and more. She also holds specialty training in cosmetic injectables and pain management injections. Outside the office, she enjoys cooking, reading fiction, and spending time with her two adult sons, two large dogs, and a kitten.
