Vis Clinic is a Functional Medicine/Nutrition Center that focuses on the whole person while treating each patient in a uniquely individualized fashion. ‘Vis’ is short for the Latin phrase Vis Medicatrix Naturae meaning the “Healing Power of Nature”.

We utilize the science of nutrition to treat sustained or chronic illness, to prevent illness, to stay healthy, and to enhance the function and quality of life through lifestyle education.  Here at Vis Clinic, we incorporate a blend of diagnostic options and solutions using nutritional, naturopathic, and physical medicines to achieve answers for your unique health situation.

To maintain your health or regain your health and vigor, we use extensive
biochemical and nutritionally based laboratory testing to discover the underlying causes of symptoms and illness. Therapy focuses on correcting the biochemical
and nutritional imbalances discovered through the comprehensive evaluation
process to bring the patient back to optimal health.



Dr. Chad Krier is a board-certified Doctor of Naturopathic Medicine, Doctor of Chiropractic and a Kansas native. Dr. Krier practices Functional Medicine utilizing extensive health history data and comprehensive functional based laboratory testing. Dr. Krier has developed a unique systems-based laboratory/Gestalt type method for analyzing patterns of functional deficiencies or excesses by creating distinct maps of each patient’s biochemical uniqueness. This approach allows Dr. Krier to map out a comprehensive therapeutic approach unique to each patient’s functional physiology. His practice relies heavily on environmental medicine and not only treating deficiencies, but more importantly looking at excesses such as exposures to fat soluble toxins, heavy metals, and GI burdens.
