In 1988, just out of medical school, Richard founded the first North American chapter of Doctors Without Borders, the Nobel Peace Prize-winning humanitarian organization that has inspired a movement among medical professionals to help the world’s most vulnerable populations. Shortly thereafter he became its first field volunteer, spending an extraordinary year in remote Cambodia; these experiences are movingly captured in his new memoir, Cambodia Calling. Hundreds of volunteers have since followed in his footsteps, bringing their healing skills to help many of the world’s most vulnerable people. Richard has been named one of Report on Business’ Top 40 Under 40 for his work. Modest and deeply passionate, he is also a renowned speaker, sharing his stories of ordinary people doing extraordinary things in the midst of war and other challenges.
