Ron Hunninghake, MD

Chief Medical Officer

Dr. Ron Hunninghake, MD, is Chief Medical Officer at the Riordan Clinic. He is a medical doctor who specializes in the care of people with chronic disease, cancer, nutritional deficiency, and mental health.

Dr. Ron, as he is known to patients, is a native Kansan and earned a bachelor’s degree in chemistry from Benedictine College in Atchison. He attended the University of Kansas School of Medicine and had a medical internship at Wesley Medical Center in Wichita. He moved to Salina for his residency at Smoky Hill Family Practice.

He has also earned a Metabolic Approach to Cancer certificate from the Metabolic Terrain Institute of Health (MATC certified) and is a certified Chelation Advanced Provider with the American College for Advancement in Medicine. He is a member of the International College of Integrative Medicine. He is also a past certified member of the American Board of Family Medicine and past chairman of the International Schizophrenia Foundation.

Dr. Ron began his career as a small-town doctor in Minneapolis, Kan., where he first started teaching clinic-based wellness. He later returned to Salina to join Salina Family Physicians, where he was instrumental in founding WellPlan, a comprehensive lifestyle modification program. He joined the Riordon Clinic in 1989 to have even greater involvement in helping patients learn innovative ways to rebuild and maintain their health.

Dr. Ron was inspired to adopt his own high-level wellness behaviors based upon a book gifted to him by a medical school surgery instructor who thought it was much smarter to prevent illness rather than wait for the worst to happen.

Later on, Dr. Riordan encouraged him to only make recommendations to patients that he himself was willing to adopt and live. After all, Dr. Ron says it is always wisest to walk your talk.

In addition to his practice at the Riordon Clinic, Dr. Ron has lectured extensively on the Riordan Intravenous Vitamin C Protocal for Cancer and has been a regular presenter at the Orthomolecular Medicine Today conference. He has traveled worldwide to present lectures in Japan, Spain, Ecuador, Columbia, India, and Canada.

At the Riordan Clinic, he has presented hundreds of lectures dealing with a wide variety of topics including nutrition, lifestyle, and optimal health. He has co-authored three books on subjects including inflammation, energy-boosting supplements, and how to stop pre-diabetes.

Dr. Ron was recognized as the Orthomolecular Doctor of the Year in 2011 by the International Society for Orthomolecular Medicine and named to the Orthomolecular Hall of Fame in 2013. In 2017, he was also recognized as a Healthcare Hero by the Wichita Business Journal.

In his free time, Dr. Ron enjoys time with his grandchildren, mowing the lawn, reading mystery novels, and travel.
