Boston, USA

I'm happiest underwater. But when I'm not poking around a coral reef, I'm into brands. Specifically helping companies build strong brands across borders. Today that means merging traditional marketing practices with a strong digital presence. I've been working with advertising and brand strategy for over 25 years in Boston, San Francisco, Stockholm and Copenhagen.

After 18 years working as creative director for some of the world's largest ad agencies I decided to start my own in 2001. Today Duffy Agency serves clients in over a dozen coutnries from its offices in Boston, Massachusetts and Malmö, Sweden. I split my time between Europe and the States.

I enjoy sharing what I've learned with others and try to do that in my blog, Brand Rants. I do a lot of public speaking on international marketing and social media. I'm also a lecturer at the Lund University School of Economics where I teach a graduate-level course on social media and international brand management.

I'm an active member and past Governor of TAAN Worldwide (www.TAAN.org). A member of the American Marketing Association, I'm also active in the Swedish American Chamber of Commerce as well as the Swedish Chinese Chamber of Commerce. Oh, and every Mobember I grow an ugly mustache.
