“David’s talk left my team excited, inspired, and most of all like they had learned something meaningful. Invisibles is genuinely eye opening and our conversations about the talk have continued ever since.”

David Zweig’s presentation was excellent and very well received by our attendees (about 2,000 people). We found David to be very easy to work with. In his presentation, he had a substantive message and an entertaining style of delivery. I give David Zweig my unqualified recommendation.
