Lumina is the largest private foundation in the United States focused exclusively on helping to create a learning system that enables more Americans to earn college degrees and other credentials after high school. We seek to maximize the effectiveness of our work through a leadership model of philanthropy, instead of adhering to a strictly charitable role. Jamie Merisotis, the foundation’s president and CEO, outlines how this model can lead to change that permanently alters the conditions that make such philanthropy necessary.
