As the CEO of the Girl Scouts, I was working to help a great organization become ‘the best that we could be’.  The first person Marshall volunteered to work with was me – this sent an important message.  I was exuberant about the experience, I improved and we moved this process across the organization.  Now I am Chairman of the Leader to Leader Institute – and we are still working together to serve leaders.

Marshall is a great coach and teacher.  He has done a lot to help both me and our high-potential leaders.  His approach is practical, useful, helpful and fun!
