My grandson had his birthday party here yesterday, it was a great experience! He is turning five, and the kids who attended ranged from about 2 to 10 or so. Master Maui did a wonderful job in making the various activities-zip line, beach ball dodgeball, shipwreck, etc.-both exciting and safe. He's a native of Hawaii and a carpenter by training, and he built out his dojo himself. Very impressive! After checking out his YouTube videos, I'm convinced that he's also well-equipped to teach martial arts and self-defense.
