Working with Dr. Kays has propelled me to achieve a greater sense of mental toughness on and off the tennis court. I take his new book ‘Sports Psychology for Dummies’ wherever I go and it’s great to have accessible knowledge at your fingertips. He has also made efforts to watch me play and has even sat in as my coach at a tournament in The Family Circle Cup in Charleston, South Carolina. He has also flown to Sweden to help me with off-season training. Dr. Kays truly cares about the people he works with and puts great effort into going the extra mile. He understands the mind of the athlete and as a professional tennis player, he has helped me master the psychological aspect of my game.
