As Dominicans we trace our roots to the 13th century when Dominic founded the Order of Preachers (O.P.). That provides us with nearly 800 years of history as members of a worldwide Dominican Family. Our U.S. congregation was founded in Wisconsin by an Italian Dominican missionary, Samuel Mazzuchelli, O.P. in 1847. Fr. Samuel, currently recognized as “Venerable,” is well on his way to being named a saint by the Vatican. Today over 400 Dominican Sisters from Sinsinawa are “called to proclaim the Gospel through the ministry of preaching and teaching in order to participate in the building of a holy and just Church and society” and minister in dioceses all over the United States and in Trinidad and Tobago.
