    I came to Chris in July of 2016 with some very specific strength and performance based goals that I had finally committed to accomplishing; since I am in the field of Strength and Conditioning and bodywork I was in search of an expert.

  • Chris Pinto

    Chris Grayson is by far the most knowledgeable professional in this field that I have ever crossed paths with. Chris has been educating me with training advice for over a decade, and he played an important part of my recovery process from knee surgery earlier this year.
