The province is composed of the metropolitan, the Archdiocese of Indianapolis, and 4 suffragan Dioceses, namely: Evansville, Fort Wayne-South Bend, Gary, and Lafayette; all in Indiana.
Archbishop Daniel Mark Buechlein, O.S.B. (69) is the ordinary of the Archdiocese of Indianapolis. He has held the post for over 15 years.
The Diocese of Evansville is led by Bishop Gerald Andrew Gettelfinger (72). He has been serving as the ordinary for over 18 years.
Bishop John Michael D'Arcy (75) is the ordinary of the Diocese of Fort Wayne-South Bend. He will celebrate 51 years as a priest this coming February. His retirement and the naming of a replacement are likely in the coming year.
The Diocese of Gary is led by Bishop Dale Joseph Melczek (69). He will celebrate his 25th anniversary of consecration as a bishop in about a month.
Bishop William Leo Higi (74) is the head of the Diocese of Lafayette in Indiana. While he reaches the normal retirement age of 75 at the end of August of the coming year, with the current backlog his retirement and the naming of a replacement may be delayed until the coming year has passed.
This province hasn't seen a change in its hierarchy in over a decade. But every single ordinary will very likely retire in the next decade - beginning with Bishops D'Arcy (probably this coming year) and Higi (probably the year after that).
