Caldwell Testimonials
“Iron is the best sports rehab around! After going to four places and getting nowhere, I was referred to Iron and everything changed. I underwent a full hip replacement and less than two months later I’m running and lifting weights.
This is definitely the place to go! It’s one-on-one and there aren’t 30 people in the same room playing with rubber bands. They’ll work you like you are an elite athlete.”
“Each and every member of the staff is amazing! You listen, care, and produce positive results. I limped in and skipped out! I am so happy to be pain free.”
