I have already dedicated 18 years of my career to business aviation and gained much varied experience during this time. I therefore thought that nothing can excite me. My believe was proven wrong in these 2 days by the Customer Service Excellence Course with Dietmar Duller because I learned a lot. Dietmar brought to our attention so many details, which were just as interesting and helpful for beginners, as for those of us with experience. His practical part of the training, especially the “performing under time pressure” exceeded my expectations! Absolutely outstanding! I was also a teacher before entering aviation and that is why I can say: “Dietmar is a talented teacher”. No one became tired or bored after 6-8 hours of classes each day. I am really looking forward to my next course with Dietmar( wine, culinary, or both)!
