It is a long way from the tranquil hills of Tennessee to the war-torn streets of Nigeria, Darfur or Sri Lanka, but that path is the one chosen by surgeon Dr. Thomas Krueger. Dr. Krueger served overseas on four missions with Doctors Without Borders, the international medical organization, and has plans to go abroad again. He is also featured in the Academy Award-nominated documentary on the organization, Living in Emergency: Stories of Doctors Without Borders. In this discussion with the Second Opinion Live hosts, Dr. Krueger speaks about what he learned, how he helped, and why this service was important for him to perform.
