Sounds like he had good technique but its unfortunate he wants to use X-rays. NUCCA might be a way to help narrow a search for a decent chiropractor but by no means am I saying all NUCCA chiropractors are good. Its best to check out each chiropractor individually. However that is not always an easy task sometimes because there are so many chiropractors out there to make a buck! The one I've been seeing sells cheap Indian herbs, uses electric therapies, and other gimics. His adjustments just don't stick and sometimes it just doesn't feel right to have somebody snap my neck real fast.
