Robert Doyle’s story is about a Concord, California, boy who loved gardening and went on to change the world. He started out wielding rakes, shovels, and chainsaws for the East Bay Regional Park District. He ended up raising a billion dollars and doubling the district’s size, making it the largest local park agency in the country.

With clever strategies and dedicated partners, he helped keep the East Bay from becoming another sprawling Los Angeles. He protected and restored places where city folk can enjoy the health-giving benefits of nature near their homes. "We need to save the earth and save the planet," Doyle says. ”And what I found out is that by doing it at home, you can make a real big difference if you stick to it. And that's what I'm going to keep doing.”
