K.S.
Definately go with Kenukan! They are about the only legitamate place around this area. They are the real deal and don't produce a bunch of "pajama dancers". They will teach your children tecniques they can actually use and make your child work for his belts. Most martial arts "acadamies" just want your check book and that is why they are constantly testing your child, since each new test costs you money.
Bob & Travis Boggs (father & son) own it and are wonderful people! They are downtown Olathe near the courthouse. Their dojo is on Kansas ave & I believe it is, Cedar street. No paper tigers is their motto.
