Almost forty years after his work with USAID, Bill Felstiner returned to this earlier vocation. During the Katrina disaster in 2005, he volunteered and worked as the director of one on the largest shelters for the homeless of New Orleans. In 2007 he founded, together with colleagues from Santa Barbara, the Chad Relief Foundation (CRF) and became its first director. The organization is a non-profit NGO, whose objective is to provide assistance to refugees from the Central African Republic in South Chad and to the local population surrounding the refugee camps.
