Holy Transfiguration Orthodox Church in Warrenville, Illinois began in 1988 through the mission work of Fr. William Caldaroni, who during his seminary years became committed to the fullness of the Faith in the Orthodox Church. Under the guidance of Fr. Peter Gillquist, Mission Director of the Antiochian Orthodox Archdiocese of North America, and Fr. Nicholas Dahdal, pastor of St. George Orthodox Church  in Cicero, Illinois, the work of establishing a parish in the Wheaton, Illinois area began. From the first location rented on the campus of Wheaton College to our present location in Warrenville, Holy Transfiguration has offered the vision of the salvation through Jesus Christ to hundreds of people: some who came without faith, some who were Orthodox from infancy and some who came to Orthodoxy from Evangelical, Protestant and Roman Catholic traditions.
 In 2007, Holy Transfiguration began a new chapter as Fr. Wilbur David Ellsworth was appointed by His Eminence +Metropolitan PHILIP and ordained by His Grace +Bishop MARK to become its second priest. After serving many years as a pastor of evangelical churches in California and the Midwest, Fr. Wilbur, under the guidance of Fr. Patrick Reardon, led a mission group of recent converts from All Saints Church  in Chicago as he began his priesthood at Holy Transfiguration. As a church we are united in our commitment to worship the Holy Trinity, to faithfully proclaim the Gospel of our Lord Jesus Christ, to preach and teach the Holy Scriptures, to build a community of prayer and love for one another and to express the love of God in Christ to those whose lives we encounter.
