Above and beyond his own foundation's efforts, Greg has collaborated with an extensive number of individuals, companies (like Jamba Juice, pictured left), teams, nonprofit organizations and schools on civic, volunteer and philanthropic projects around the USA, Canada and Africa.  In Minnesota, for instance, he teamed up with the Minnesota Vikings. In conjunction with his visit to speak at an event for local Mayors and at a local middle school, the team ordered copies of The First Thirty for one class of students and sponsored a community service essay contest based on the book for those students. In some cases, Greg has been asked to serve as a resource for advice and consultation for other individuals, organizations and corporations   who are engaged in civic, volunteer and philanthropic efforts.
