Dr. John McKeown                  

Dr. John McKeown is a family practice physician who strongly believes that the patient should take responsibility for their own health. He has sponsored a number of health programs designed to improve the health of the community. Most recently he teamed up with the Wickhams to develop and present Grundy Reversing Diabetes Seminars to the people of Grundy County, Tennessee.

Grundy Reversing Diabetes Seminars (Grundy RDS) is a community-based education program that focuses on diabetes prevention and reversal. It was developed by Stephen after learning that their county had the lowest health rankings in the State of Tennessee.

Within these roles, both Stephen and Karen have cared for diabetic patients and assisted with educating them about the disease, how to care for themselves at home and also what to expect when having diabetes. They have cared for patients who have developed the complications of diabetes such as amputations, kidney failure, strokes and heart attacks. When they learned of the needs in Grundy County, they felt compelled to do something to help their community. Thus, Grundy Reversing Diabetes Seminars was born.
