After spending five years in Brooklyn, New York, occasionally working as a restaurant waiter, Préval returned to Haiti and obtained a position with the National Institute for Mineral Resources. In 1988, he opened a bakery in Port-au-Prince with some business partners. While operating his company, he continued to be active in political circles and charity work, such as providing bread to the orphanage of Salesian Father Jean-Bertrand Aristide, with whom he developed a close relationship. After the election of Aristide as president in 1990, Préval served as his Prime Minister from February 13 to October 11, 1991, going into exile following the September 30, 1991 military coup.
