Jacqueline Golay, Senior Corporate Flight Attendant, Switzerland, August 2011

Dietmar Duller is an outstanding character, who brings private aviation exactly to the point. Attention to detail is an absolute “must” in business aviation in order to differentiate oneself as an individual and a company. All of these facet’s are demonstrated in the course and are professionally presented. Dietmar Duller knows how to motivate training participants and even to shape their individual contribution in advance in order to better respond to the respective customer.
