If you’re looking for the model of a compassionate doctor, you could start with James Orbinski. As a former member – and president – of Doctors Without Borders, also known as MSF, he’s served in some of the world’s most chaotic places, like Somalia, the refugee camps of Afghanistan and Rwanda, both before and during the genocide. He writes about his experiences in the book “An Imperfect Offering.” He told Steve Paulson about the moment he realized what he was capable of contributing, as a doctor.
