Dieter grew up in Belgium where he attained his bachelor degree in education. After spending some time in the military, he worked as a high school teacher for several years, but every minute of his free time was spent out in the remote and mountainous regions of Europe. Always one for taking initiative, Dieter took several courses and eventually attained a UIAA Instructor Mountain Walking & Trekking qualification. As an instructor for the Flemish mountain sports federation, he set up several trekking tours in the European mountain ranges, organized orienteering & adventure weekends, and taught workshops on orientation.
He fell in love with Iceland through snowshoe guiding. On any given day, you can find him guiding on the glaciers or on backpacking trips in Iceland's rugged interior, and in his free time, he's more than likely planning his next trip.
