Retail Wentworth Gallery When Wentworth Gallery wished to expand from 6 to 40 locations, they turned to GSD. With an established track record in retail construction, GSD was awarded an exclusive contract to provide design/build construction services in major malls nationwide. GSD also helped refine the design of the unique Sliding Display System (lower right).
