"Dr. Dave Sahley, basically saved my life. After an unusual ADR spine surgery overseas, and me being a very complicated case, Dave took the time very cautiously to assess, treat, and have a regimed 4 month protocol. He did wonders for me, and got me a functional life back (which I never though I would ever gain). I’ll be forever grateful for Dave, along with the entire staff. Other PT’s royally treated me like an assembly line, didn’t understand the anatomy, made me worse, along with not knowing how to treat ADR (which is a completely different approach than a fusion). His knowledge, skills, one on one approach, and attentiveness were bar none amazing! His name goes down in history as “ Diamond Dave!!” Thanks again dynamics PT!"- Jordan K.
