Catawba Valley Potter
aka Ron Jordan or Ronald Jordan
Collaborated with Joe Reinhardt at least in 2004 and in 1996. According to at least one ebay listing he was Joe's assistant for several years, fired his work in Joe's kiln and decorated many of Joe's pieces. Obviously don't take ebay listings as gospel, but it sounds plausible and is a good place to start absent any real sources.
Also did (does?) his own work, at least in 1997.
