In this episode, I talk with John Williams about his unique approach to coaching, training, and mentoring athletes. At the core of his teaching is the Hippocratic oath. He discusses how he adapts and adjusts to various athletes from different athletic discipline, including NFL players, ballerinas, and even exotic dancers. He touches on his approach to building trust among his students, and how that helps him reach students with more complicated backgrounds. We land, at the end, on tennis and some of its current stars, including Novac Djokovic, Rafael Nada and current US Open champion Coco Gauff.
