Dr. Nguyen and his Stem Cell Therapy has had miraculous effects on my Knees. I suffer from significant Arthritis in my Right knee and the 2 PRP Shots I have received has me walking much more and with less pain. I will be having more PRP and Stem Cell Injections down the road but these doctors are fantastic. I drive from Murfreesboro, Tennessee to get these treatments. I would not do that if it were doing me no good.
