While performing in films and training for marathons, I suffered disk herniations. I was a mess-pain, atrophy, weakness, numbness. Once the Whartons got their hands on me, I was right back on my feet. I was blown away by the knowledge, passion, and commitment that Jim and Phil have for what they do.
