Ultra-luxury Silversea Cruises announced that it is expanding its executive team with the appointment of Tom Russell as its new senior vice president of product development. He will join the company on October 14 and will be based in the Fort Lauderdale office. His appointment follows on the heels of the line's recent purchase of the expedition ship World Discoverer. While Russell will coordinate a variety of major projects and initiatives across departments, his primary focus will be to oversee the establishment of the new luxury expeditionary cruise product, having responsibility for its design, deployment and itinerary development. Russell is no stranger to Silversea.
