Fr. Donald Calloway, MIC, born in 1972 in Dearborn, Michigan, is a convert to Catholicism and is now a prominent Marian priest with the Congregation of Marian Fathers of the Immaculate Conception of the Most Blessed Virgin Mary.  This congregation is totally consecrated to Mary Immaculate, faithful to authentic Church teaching, obedient to the Pope and Magisterium, and intensely Eucharistic. He speaks passionately in his moving conversion story from high school dropout who had been kicked out of a foreign country, institutionalized twice, and thrown in jail multiple times to earning a B.A. in Philosophy and Theology from Franciscan University of Steubenville, M.Div. and S.T.B. degrees from the Dominican House of Studies in D.C. and an S.T.L. in Mariology from the International Marian Research Institute in Dayton, Ohio.

Fr. Calloway’s unmistakable zeal for the priesthood and devotion to Our Lady as led him to author or edit many articles and books on the Blessed Virgin Mary and he travels throughout the country to talk about his favorite saint and devotion (the Rosary).
