  • "After three marathons in the past year, culminating in the Beijing Olympic Games, I was ready for a good break. Subsequently, after two weeks of not running I was in much need of some therapy. I spent a week with Tom Nohilly at the Wharton Performance Center going through their unique flexibility and strengthening techniques. I am now feeling ready for the hard training for my next marathon. Their method is simple, yet brilliant. Isolating the specific muscles used for my sport that are in much need of strengthening. I am confident that if I apply the techniques I have learned it will greatly increase the longevity of my career. I feel blessed to have the Wharton's and everyone at the clinic as friends."

  • "Jim Wharton is special. He understands all the important aspects of musculoskeletal pathology. As a physician, I can comfortably say he knows human anatomy better than most orthopedic surgeons. By way of example, Jim not only has an understanding of the insertion and attachment ligaments, tendons and connective tissues, he also understands how multiple tissue layers are aligned and oriented about the inner skeletal support system." I have been going to see Jim for over a year. Perhaps the best testament to his skill and expertise is that I need him far less than I did one year ago and have developed the needed skills to not only maintain a healthy physical condition but also improve my musculoskeletal health. Above and beyond his level of competence are his demeanor and the way he interacts with with his patients and friends alike."

  • The best thing that's happened to me during my running career was being able to be treated By Jim and Phil Wharton. Their stretching therapy has helped me recover faster from injuries and from my stressful training. With their therapy I am able to train better due to increases in my level of flexibility and strength. I have captured 2 World Record's in marathons (2h05:42/2h05:38) while in the care of Jim and Phil Wharton. This is a stretching technique that I will never stop receiving during my career.
