Contributing to the development of our region

The foundations of thg were laid 35 years ago, in St. Vith. Today, after creating more than 10 offices in Belgium and the Grand Duchy of Luxembourg, St. Vith is not only the headquarters of the group, but remains an important point of contact for the companies and individuals from the South East of Belgium


Since the middle of the 80s, our St. Vith office has supported many companies that are currently considered as flag-bearers of the economy in the East of Belgium. This success often goes together with the establishment of a parallel entity in the Grand Duchy of Luxembourg. thg has also established its most prestigious office there. The founder and CEO Joseph Faymonville is the senior executive of the group. The management of the office of St. Vith is provided by Kurt Leinen, who has worked for thg since the end of the 80s.
