I was in a neck brace and had MRI and CT and was told I needed surgery for my cervical spondylosis. I was in pain from years of working at a computer but the pain was so intense now I couldn't take it. All the Doctors I've seen just want to prescribe pain meds and Surgery was my last resort as I work at a hospital and hear horror stories. I had seen a couple Chiropractors and they didn't do anything for me.

A co-worker recommended Dr. Penniston, so I made an appointment and so glad I took one last leap of faith because after just a couple visits I left pain free after years and years of constant pain I couldn't believe it. He really was my Life line. His knowledge of body mechanics is unprecedented. It's been years and I haven't had to have surgery and if I start to feel any pain I make an appointment and leave pain free. He has done more for me than any other Health care worker I've seen.

This place is amazing! I have lived with hip, back and leg pain for over 20 years and Dr Penniston found the route of the problem and treated me. I went about 6 times, he gave me stretches to do daily and I now only go to stay in alignment. I wish I would have discovered him years ago. What a life changer.

Greg is very good at manipulation. He is not like the cracker packers that I have gone to before. Very gentle in adjustments. He believes in muscle testing and even though it seems weird it works and so do the supplements. I have been going to Lifeline for many years and have recommended Greg to several of my friends. He is the only Chiropractor that I have not had to visit on a regular basis, which to me means that he is doing a great job. I go for a tune up about every other month. Really would recommend to anyone who needs a good chiropractor.
