'The One-Company Leader'.

I first met John Seifert in 1983. We were both working at Ogilvy & Mather in New York on the TWA business. The world was very different back then.

What hasn't changed much is John.

John and Ogilvy always seemed to fit together. You couldn't imagine hime working anywhere else.

Thirty nine years later, he still hasn't. Today he is the company's CEO.

In an era and industry defined by upheaval, I wanted to talk to John about why he has stayed at one company for so long.
