I recommend that you check out Chamberlain Studios of Self-Defense www.dallaskenpo.com/. My son has been learning Kenpo style karate there since he was 4. He is now 6 1/2 and has always had a number of girls in his classes who participate and respond to Sensei on par with the boys in the class. Sensei Rollend is simply amazing with these young children. He will sometimes have 15 in his class, and usually at least 5 or 6 are girls. He has a way of keeping them all occupied and on task learning the different kata, answering questions about their character lesson for the month and enjoying the whole experience.
