Stewart Resnick, the chairman of privately held Roll International Corporation, and his wife, Lynda, are serial entrepreneurs. Not only have they established several very successful companies, they have also used their wealth to support medical research, education, and the arts. Being able to create successful strategies, not just once but over and over again, is a rare skill. And it is clear that their skills are not rooted in any one industry—they have been able to succeed in alarm services, flower delivery, collectibles, agribusiness, and bottled water.
