Kru Stevenís knowledge of Muay Thai greatly exceeded my expectations. He breaks down each punch, kick and defensive maneuver into itís smallest component so that even a beginner like me can easily understand. His patience with each student is a trait that I respect tremendously. Iím amazed at how much progress Iíve been able to make in only a few months.
