ess careless careless 15 years as a law officer an now im forced into early retirement. this doc doesn't take accountability for his failures. I kept telling him I had major pain and problems. He Never wanted to order second mri to expose his failure in surgury. Keep away from him. He won't do anything to help. Got second option an of course he left me worst then I allready was. For your family health an wellness STAY AWAY
