Greg has collaborated with many individuals & organizations (e.g. In conjunction with an event where students read The First Thirty, he collaborated with the New York Giants on a community service essay contest based on the book for those students). He has collaborated with many organizations (e.g. Chambers & CVB's) as part of The Elevator Project. On many occasions, he has helped connect two parties to facilitate their collaboration on their own project. For example (photo), he connected a school for kids with learning differences - with - a nearby retirement community. The kids' art went on exhibit in the retirement community, and the residents helped the kids with their reading. In another instance, he connected a nonprofit with an entrepreneurship program at a nearby university. The nonprofit's founder spoke at an event for the program's students. In turn, the students volunteered their time to assist the nonprofit. During the Pandemic, Greg collaborated with groups all around the nation and elsewhere on additional projects.
