I couldn't recommend bio resonance enough. I have secondary breast cancer and suffer with painful symptoms and lack of energy. Since having weekly sessions of bio resonance my energy levels have greatly increased. I also believe in keeping my body as healthy as possible in order to cope with the disease and treatments and bio resonance helps immensely to improve my immunity. I have recommended that my friends and family all have sessions periodically to prevent illnesses in the future. There are no nasty side effects and spending an hour in the company of Chris or David for an hours therapy is an hour well spent. Both are very knowledgeable within their field.
