This document provides an agenda and overview of a summit about volunteer engagement between Groupon and the Girl Scouts of Greater Chicago and Northwest Indiana. The agenda includes introductions, presentations on each organization's volunteer programs and best practices, and an overview of their joint "Scout Out Engineering" program for girls. The program has engaged over 450 girls and 175 volunteers since 2013, building STEM activities like popsicle stick bridges. Plans are to expand the program to more cities in 2017 and deepen the partnership between the organizations.
