On "American Pickers", if Danielle runs the store in Iowa, who runs their Nashville store?

One person running it is Lauren Wray Grisham:
"The staff is equally as helpful. Lauren Wray Grisham is a wealth of information. As the assistant manager, if she is unsure of an items provenance, she has the courage to say she doesn't know, but she knows where to find out. And she does." -from http://www.urbanartantiques.com/2011/american-pickers-and-antique-archaeology-comes-to-nashville/

"Local Nashville resident, Lauren Wray Grisham, has landed a major role on HISTORY's American Pickers. Mike Wolfe, the star and creator of the hit show, recently opened an Antique Archaeology shop in Nashville. The store is located in the old automotive plant in Marathon Village. It joins the original Antique Archaeology in Le Claire, Iowa as a focal point of the American Pickers adventures. Lauren is one of the Nashville store's managers and has already filmed four episodes. She was hired on the spot just this year by the siren of rust, Danielle Colby-Cushman." -from https://nl.player.fm/series/firepit-friday/lauren-wray-from-antique-archaeology
