Whitney Painter spent a decade in Washington DC, and was fortunate to gain experience from a variety of angles–CNN, the U.S. Senate and a range of environmental and women’s issues organizations. It was a great experience and she gained a genuine appreciation for the idea that each of us should participate in the policy process–from the most local to the broadest national issues–because these things truly affect our daily lives. We may not always get the outcome we seek, but every once in a while it’s possible to make an essential change or difference, and this makes the entire effort worthwhile.

Currently, Whitney Painter and Bart Sheldrake are co-owners of Buglet Solar Electric, based in Golden, Colorado.
