A firm believer that the body has an incredible, innate power to heal itself, Dr. McKinzie knows that this can only happen “if nothing interferes with that healing.” He will tell you that small miracles happen daily within his practice, from stopping migraines, to preventing back surgeries, and all sorts of issues in between. Our nutrition patients lose weight, get rid of heartburn, allergies, GI distress, brain fog, hold their adjustments longer and top it off with better quality sleep, more energy and a better sex life.”


Dr. McKinzie received his B.S. degree from Missouri State University with a major in Biology and minor in Chemistry and in 1990 my Doctor of Chiropractic degree from Parker College of Chiropractic in Dallas, Texas. READ MORE
