Meet the Team

For a book to reach the heights of influencing business culture throughout the world, it takes more than a couple dynamic and talented authors, it takes a team. This list doesn’t include the many friends and colleagues that have reviewed and endorsed The Go-Giver, the publicists and marketing teams that are connecting us with new audiences, or the many Personal Walking Ambassadors who are sharing The Go-Giver with their friends and constituents. It does, however, include the core team members who have been vital in taking a great manuscript and helping it become a clarion call for a somewhat revolutionary way to do business.
