Advanced Mindset was developed through mutually beneficial interactions between Dr. Gassaway, a range of athletes, multiple coaches, several clubs, and parents. It became apparent that the skills presented by Dr. Gassaway could be applied broadly and enhance the performances of all who invested time in themselves using the tools provided.
