Deeply optimistic, I’m an author, educator and speaker; I call myself a champion of social good. Through my work, I hope to help solve some of the world's biggest problems--poverty, disease and climate change. My books—read over 1 million times—on using money for good, personal finance, crowdfunding and corporate social responsibility draw on my experience as an investment banker, CFO, treasurer and mortgage broker. I have delivered a keynote speech at the United Nations and spoken in countries from Brazil to Russia and across the US. Previously, I worked on the U.S. Senate Banking Committee staff and earned an MBA at Cornell.
