Jim Gregory and his wife had rocked along in their ad agency on Madison Avenue for 20 years, enjoying the creative work and their clients, but they suffered from lack of differentiation from competitors. After much thought, they decided it was time to apply to their own business the best advice they gave their clients. Today as chairman of Tenet Partners, a global brand strategy and marketing firm based in New York City, Jim is a leading expert on measuring the power of corporate brands and their impact on financial performance. He has written 5 books on branding.
