He has also taught karate to the families of many notable people including Steven Spielberg, Norman Lear, Barry Levinson, and more.

One of our students, Ernesto Matamoros, won 3 Olympic gold medals in the Beijing 2008 games, which is notable since Wushu is the national sport of China. We're looking forward to when karate is included in the next Olympic games in Japan.

Fred Weintraub, producer of Enter the Dragon, noted that “Keith Cooke’s feet are as fast as Bruce Lee’s hands.”

Mr. Cooke also has a passion for fitness. His high-energy adult fitness classes are designed to burn fat and build muscle while focusing on core strength, flexibility and cardiovascular health. Mr. Cooke has trained and prepared several movie stars for their roles and has personally starred in films such as Mortal Kombat, Beverly Hills Ninja, Heatseeker, Born to Ride, China O’Brien, King of the Kickboxers, and more.
