"Christopher helped me with the preparation of my talk at TEDxBerlin 2014. His coaching comprised not only delivery techniques and impact but also especially the shaping of the storyline. I am convinced that the joint work advanced and improved my talk considerably. And more than that: it also sharpened my eye for good speeches and has massively influenced the way I approach talks and presentations since then. Christopher taught how stories can come to life via discontinuities and leaps. And he gave me the courage to show more of myself on stage. As a speaker I feel more authentic and that hopefully has also an impact on my audience."
