Hey Kaizen,
Kelly has a degree in physio therapy from Samuel Merritt College in Oakland, but I have to assume that only laid the foundation for his current knowledge base. Truthfully, becoming that knowledgeable and skilled takes a potent blend of passion, curiosity, critical thinking, and experience. With his involvement in athletics and CrossFit, Kelly had a more intimate understanding of the needs of athletes than many therapists have, especially early in their careers. He saw problems in the system and has made a tremendous effort and put a ton of work out there to try to fill those gaps, things like teaching people to move better, to respect good movement, and giving them the tools they need to perform their own maintenance.
Passion and experience, my friend. That is how you become an expert.
