Dr. Olawale Sulaiman, 41, is a professor of neurosurgery and spinal surgery and chairman for the neurosurgery department and back and spine center at the Ochsner Neuroscience Institute in New Orleans. He lives in Louisiana, but splits his time between the US and Nigeria, spending up to 12 days each month providing healthcare in the country of his birth — sometimes for free. Born in Lagos Island, Lagos, Sulaiman says his motivation comes from growing up in a relatively poor region. In 2010, Sulaiman established RNZ Global, a healthcare development company with his wife, Patricia. The company provides medical services including neuro and spinal surgery, and offers health courses like first aid CPR in Nigeria and the US.
