Derek is a great martial arts instructor and a patient teacher. He doesn’t look down on anyone who is a beginner and sees the potential in everyone who is willing to learn. He boils down basic principles to make them easy to digest and take in while at the same time encouraging his disciples to keep at it, and maintains that they continue to practice to improve. Derek pinpoints areas you need to work on, down to very accurate details of posture and motions, and explains the reasoning and theory behind the movements, so that when you’re practicing and training, you have a clear understanding of why Wing Chun works the way it does as a martial art. He is very knowledgeable and a genuinely kind trainer, and I always find I learn something new, or come away better prepared after a session.
