I have a 15 years experience of training in better presentations. Prior to that I was a research scientist. I moved from that into presentations when I realised that we didn't need "new science" as much as we needed people to understand and apply what science already knew.
I'm the author of a number of books on presenting (some best sellers, some sank without trace!) and I've worked with clients from start ups to multinationals such as Dell.
I've also worked as an actor, playwright, lighting designer and fire eater!
Oh, and there's a bunch of testimonials at presentationgenius.info/training-testimonials
