Your brain monitors and controls every cell in your body. Pain and disease are caused by from breakdowns in the signaling between the brain and muscles, joints, organs, and glands, or from emotional distress. NIS uses gentle muscle testing to find and fix neurological interference, allowing your body and mind to tap into their own healing powers. The NIS System was developed in New Zealand by Dr. Allan Phillips and used across the globe. Dr. Jim Bentz is the only certified NIS instructor in the U.S.!
