NEW YORK – Second careers are now the norm. Stephanie Case, co-owner and vice president of operations at Case Antiques, Inc. Auctions & Appraisals in Knoxville, Tennessee, and her husband, John Case, are a fitting example of the phenomenon. Each had a different career before launching their auction business in 2005. His was in biomedical and biotechnical engineering, and hers was in retail management. Their auction house has grown to include three satellite offices in Tennessee, and online platforms such as LiveAuctioneers has expanded Case’s reach across the globe.
