Carroll Dorgan was born and educated in the United States and initially pursued a teaching career for a decade in international schools in Iran, Belgium, England and France. He then returned to California to qualify as a lawyer but soon moved back to Europe to practice international law in the Netherlands and France. In all of those places, he explored nearby hiking trails. Over the years, the GR5 became Carroll's favourite trail and he wrote a Cicerone guidebook for the northern part of the route. Then he discovered Brittany and with each hike on the magnificent Breton coast, he became keen to learn more and to share his love of the region with Cicerone's readers.
