Bishop-designate Choby, 58, succeeds Bishop Edward Kmiec, who was appointed last year to lead the Diocese of Buffalo, in New York state. The Vatican press office announced the new appointment today.
Father Choby was elected by the College of Consultors as diocesan administrator of Nashville in November 2004.
Born in Nashville in January 1947, he studied at St. Ambrose College in Davenport, Iowa; the Catholic University of America, in Washington, D.C.; and the University of St. Thomas Aquinas (the Angelicum) in Rome, where he finished his licentiate in canon law.
David Choby was ordained a priest of the Diocese of Nashville in September 1974.
After ordination, he held a variety of pastoral and administrative assignments. He was on the faculty of the Pontifical College Josephinum in Columbus, Ohio, from 1984 to 1989.
The Diocese of Nashville has a Catholic population of about 72,250 in a total population of 2.1 million.
