Michael is also a public speaker and speaker coach. He has spoken at TEDx, in front of members of parliament, universities, and once in a cinema full of 500 kids high on sugary popcorn. Clients he has coached for presentations have been featured on NBC, Fast Company, Forbes, and the Oprah Winfrey Network.In a previous life, he was a character animator working on award-winning movies and TV shows like “The Penguins of Madagascar” and “Kung Fu Panda”.
