Kerstin Pettenkofer guided us through the process of introducing sustainable event management. Her excellent expertise and her keen sense of working in groups were an asset to us. Change processes require attention, patience and humour. Kerstin Pettenkofer has the moderator gene. With her, the elements in the room flow together. We were able to experience how we can accept our challenges in a solution-focused way.“
