My dojang is with a small (well not really small) org. Tae Kwon Do Won ( http://www.ustw.org/ ). We basically do WTF style forms and sparring (before BB), but the org allows the schools to mix whatever they want in. They are big on putting self defense back into TKD. Which we do a lot of.
I have to recommend my own org, the World Tae Kwon Do Association. We've got a lot in common with TSD, as our Grandmaster split with the KTA way back in the day, when they started to became sport oriented. No Olympians with us though.
Similar to us is the Chung Do Kwan Alliance which split from the WTA some years ago.
Kang Duk Won and the American and German off-shoots aren't all that bad. There's also the independent dojangs that pop up now and again across the country and globally. You just have to drive around and find them.
Of course, there's also the McTKD schools... *shudder* TigerDen in D.C. *bigger shudder*
