Sunni Brown is a business owner, creative director, speaker and co-author of one of Amazon’s Top 100 Business Books titled GameStorming: A Playbook for Rule-breakers, Innovators and Changemakers. She’s best known for her large-scale live content visualizations, and she is also the leader of The Doodle Revolution – a growing effort to debunk the myth that doodling is a distraction.

Using common sense, experience and neuroscience, Sunni is proving that to doodle is to ignite your whole mind – a concept she’ll reinforce at the TED Conference in Long Beach this year (whoo!).

She will teach the world how to master “strategic doodling” in her 2nd book, The Doodle Revolution. But until the book exists, Sunni is content to interview, speak and write articles on the power of visual thinking.

Sarah Marquis first began exploring when she was eight years old - she took off with her dog to spend the night in a cave and didn’t tell anyone where she was going. At seventeen she crossed the Central Anatolia (Turkey) on horseback, without knowing how to ride.

She has travelled through Australia, New Zealand, the wild lands of Patagonia, and Moorea (French Polynesia). She explored Canada by canoe and in 2000 she crossed the United-States, from Canada to the Mexican border… 4,260 km in four months and six days.
