In conformance to your wishes and within the context of your event, Koller slips into various roles. As a butler, waiter or "man with a dog", for example, he explores for you and your guests the comical aspects of what it means to be human. With expressive language and persuasive pantomime, he gives pleasure to the senses while unleashing laughter and amazement. With a ready and reliable command of language, he attends to his international audience with English, French, Bavarian, Rhenish and above all Swiss German, his secret mother tongue. Ten years' residence in the Swiss Confederation made an original figure out of him. It goes without saying that Koller, experienced as he is in multifaceted modes of performance including television and film, brings your concepts and projects to fruition with the same creative verve.
