In a rousing call to action at the Encore Careers Summit, Gara LaMarche (at left) urged older Americans to heed the call to service that was a hallmark of President-elect Barack Obama’s campaign as well as push for policy changes that will help launch encore careers. His speech was featured on the home page of The Huffington Post.

As president and CEO of The Atlantic Philanthropies, one of the few foundations focused on aging, and as a former leader with Human Rights Watch and other organizations working for positive social change, LaMarche has watched social activism ebb and flow in many countries.

“Make the most of this moment,” he told the audience. “Respond to the call of a new president when he asks what we can do for our country, a country in which many of us are happily surprised to find we take a newfound pride.
