Excellent Chiropractor - great results!. I have had chronic head and face pain and numbness in my neck and fingers for over 2 years. I have seen a neurologist, osteopath, physical therapist, behavioral therapist and chiropractors with no results. Dr. Oncken was THE ONLY doctor to identify and alleviate the pain with chiropractic care, and physical exercises in only two weeks. His knowledge of the relationship between the spine and the supporting muscles is exceptional. Dr. Oncken is always positive, friendly and informative. I highly recommend him. Jill B.
