My brother went here for over 6 mo. and felt worse after every session. He then went for a 2nd opinion. A Dr. Specialized in the area looked at his neck and told him it was herniated and more damage was being done by manipulating it the way Glass was doing. He also strongly suggested I never go back to that chiropractor. The sad part is Mr. Glass also took cervical X-rays and supposedly reviewed them, but still went on and«cracked» my brothers neck despite the herniation. I highly recommend staying away for your healths sake.
