When Dr. Lonner originally showed me the Xrays of my back, it was a disaster. I even cried when I saw it.... Dr. Lonner not only treated me but also he gave me another life. He’s not only a doctor, he’s something more than a doctor...

"The first thing that struck me about Dr. Lonner was that he looked at my Xrays and didn't say, "I never thought I'd see anything like this," which I've had several surgeons say. He looked at everything and said, "I've got a plan." From 1-10, prior to surgery, I was at a 9 in pain. Now I'm at a 1."

"It is hard to express in a few sentences how this surgery has changed my life. It has given me the ability to participate with family and friends with greater self esteem and stamina. I can walk without pain and shop until my daughters drop. I can wear clothes that accent waistline rather than clothes that hid a deformity. I no longer worry that my curvature is progressing. I feel like a new and energized woman. Is is not easy task chossing to have an nine hour surgery,but I encourage you to trust Dr. Lonner's expertise. You will find and look so much better. Thank you Dr. Lonner for giving me new life!".
