I am a 23 year veteran of the Sacramento Fire Department who sustained a significant back injury.(L5/S1 herniation) and was close to a forced medical retirement. John Hoffman researched my injury and put together a comprehensive physical rehabilitation program that got me back on my feet and back to the firehouse. I still use his routine today and not only am I better, but my core is stronger than ever and I'm pain free. I've been through our traditional medical system with this injury and it failed me but I succeeded with Coach Hoffman's expertise!
