I have worked on community-based design projects throughout my career. I believe strongly that designers should engage with the broader issues that directly impact their own communities. Many of the past projects I've worked on have been education related- city of Chicago schools or schools where my daughter was enrolled.
Recent community-based projects include:
The Art of Science Learning: http://www.artofsciencelearning.org/
The Good City Group which is described as: a multi-stakeholder collaborative organized by Archeworks, a Chicago-based design educator that inspires collaborative action to shape more sustainable, equitable, and healthy communities.
