When I first came to see Dr. Mark, I thought I was in a pretty good state of health. After my first visit he gave my test results and explained what was going on and what I can do to feel better. So here I am a few months into my sessions and I feel GREAT! Sleep better, my eyesight improved, I hardly use my CRT (corneal refractive therapy) lenses, usually put them on every night, now it's 1-2x a week. No more calf cramps. I can run and play with my grandkids or play ball. Life is good!
