Yep, that's Gracie jiu-jitsu under Rickson Gracie's line.
Kenpo is very cool! I work with several police officers in the area and use a combination of the kenpo, ground fighting and the stick fighting (arnis) to incorporate moves into what they do. The mix of kenpo and brazilian jiu-jitsu seems to be a fantastic combination.
I also do women's self-defense awareness and rape prevention seminars for local church groups about once or twice a year.
I have a friend in Connecticut that runs a school under Steve DeMasco's United Studios. They do a form of Shaolin Kempo. IS that similar to the system your cousin's daughter studies?
Ok...done rambling. If I get started it's hard to get me to stop.
Later!
