Do you have a chronic illness Dr. Otis is a Chiropractic Neurologist and does not practice chiropractic in a way I was familiar with. Instead he uses resistance testing to determine how different stimuli affect your body (I call him my quack doctor because of this). I can't tell you why what he does works, only that it has helped me tremendously. I was recommended to him by a friend who was happy with the results she saw and recommended him to a friend who is happy with the results she saw. If you have a chronic condition that western medicine can't seem to get under control you may want to give him a call to see if he can help you.
