What is the best part of doing pro bono design work in the community?

“HOK IMPACT provides the framework for social engagement to provide better service for our communities. Through volunteer and pro bono projects, we have the opportunity to strengthen our overall design impact. Developing a more intimate knowledge of our local communities enables us to create a positive ripple effect in both our pro bono and for-profit work.”
