    Dr Aoki is very knowledgeable and explains things in a way that are easy to understand. He made sure I was taken care of before, during, and after surgery. At 6 months post op, my pain has decreased significantly, my incisions healed perfectly, and my physical abilities have improved since before surgery. Working at a physical therapy clinic and having friends who have also seen him, I've heard and seen nothing but good things!
