Excellent teacher of all things dance & clog and she is in South East."

Yes, excellent indeed - from the website she appears to teach modern Appalachian 'clogging'. I'm not sure that this is what the OP is looking for though. Although it is great to watch and do, I'm not sure that you can dance modern Appalachian step dancing in English clogs!!!
