Garrett Thornburg, chairman and chief executive officer of the Thornburg Cos., Santa Fe, N.M., was reeled into fly fishing about 20 years ago.
A friend suggested he test the waters shortly after he'd started his own investment company in 1982. Learning the flow of fly fishing was difficult in the beginning, Mr. Thornburg said. "This is a sport that takes a lot of patience. You really have to concentrate on what you're doing or it won't work."
Mr. Thornburg said he tends not to mix business with the pleasure of a fishing trip. One of the biggest fly-fishing draws is the "Zen, meditative experience" the sport offers, he said. "You're a better businessman if you're healthy and thinking clearly than if you're stressed out."
He has founded three companies: Thornburg Investment Management, established in 1982, which now has $13.3 billion in assets; Thornburg Mortgage Corp., established in 1993, now with $29.2 billion in assets; and broker Thornburg Securities Corp., which launched in 1984.
He recently traveled to the Patagonia region of Chile and Argentina and fished on the Corcovado River. Mr. Thornburg said future itineraries could include trips to Alaska and Siberia.
