Our listeners are certainly familiar with the Peace Corps and the National Peace Corps Association is effectively the alumni association for all Returned Peace Corps Volunteers. Our guest today is David Fields with the NPCA who serves as their "Social Entrepreneur in Residence" -- bringing new ideas and models to nonprofits. There's nearly 225,000 returned Peace Corps volunteers with experience working with tough problems in often difficult circumstances and he helps bridge the gap between their experiences and people trying to solve problems from a distance. He works to help nonprofits stay relevant and limber by applying methods used for venture capital to nonprofits. David Fields is a traditional analyst for the National Peace Corps Association by day and instigator of special projects for the association by night. Over the past 6 months his work has been highlighted in time magazine, popular science, and the guardian. The National Peace Corps Association is a membership organization that works to advance Peace Corps-inspired initiatives. Nearly 220,000 strong, the NPCA is a growing force for good.
