Testimonial
Working with Stefan helped me significantly improve my game, especially my forehand, which became a key weapon in winning college matches. Stefan has exceptional technical knowledge, and his biggest strength is his forehand, which he knows how to transfer and adapt to different playing styles. His coaching is clear, detail-oriented, and immediately applicable on court.
