"I was down and out with a calf tear 3 weeks before the Olympic Trials this year when I saw David Campbell (2012). He was able to turn a 4week injury into only having 8 days off. I made it to the start line and won the trial qualifying for the Olympics beating the Olympic gold and silver medalists in the process.”

“David Campbell was not only a top athlete, he is also a top physio and person. He was my personal physio in Morrocco during my pre Moscow 2013 altitude training camp. His knowledge, professionalism along with his extremely strong work ethic is second to none. I hope people appreciate the expertise and motivation that David has to offer.”

“Dave Is the most thorough therapist I have ever seen, I always feel like he is doing everything he can to help me and get me back running. His treatment at the start of this year ended a 4 month struggle with injury and now I'm back training without a problem.” (2014)
