Shawn Knowles is a self-described old-school butcher and owner of Old Town Market in Lewisville. He began working at the shop when his father first opened the market back in 1977. Knowles takes pride in learning how to butcher "the old-fashioned way," and he sees a lot of meat come through his shop.
