Diethelm Travel Group

From its first halting steps over 5 decades ago, Diethelm Travel Group has grown to be one of the largest and most important inbound tourist operators in Asia, handling 500,000 leisure and business travellers every year. While travel is the company's business, and Diethelm now employs some 600 people in 12 countries, it still definitely calls Thailand home. Diethelm Travel has grown up alongside the kingdom's tourism industry, from those far-off days in the late 1950s when visiting Thailand was still an exotic experience for only a handful of adventurous or rich travelers.
