Meet Our New Bishop!

With the ordinations of five new bishops in our Archdiocese, Bishop John Siemianowski is now the head of our Vicariate (geographic region). Bishop Siemianowski began his assignments as Auxiliary Bishop on March 1, 2025. May God bless our new bishop in his daily work and may God’s Grace draw him ever closer to Christ.

Bishop Siemianowski was born in Chicago and attended Mundelein Seminary. His pastoral assignments and ministry have kept him in the Chicagoland area. His final assignment before being appointed bishop, was as pastor of Saint Juliana parish in Chicago (2021-2025).​

🛡️ Bishop Siemianowski’s Coat of Arms:
The design is reflective of his ethnic heritage and the God who is constantly creating things anew. The colors of red, blue, and white are a subtle nod to the flags of both the Czech and Polish Republics. The upper left of the shield represents a lake and the bishop’s love of water. The fish in the lake, along with the basket of bread in the upper right of the shield is symbolic of God’s continual feeding of his people.

The six-sided star in the center of the shield is symbolic of Chicago. It also is symbolic of the six Siemianowski brothers and sisters. The tulips in the lower third of the shield are symbolic of God’s creation and the bishop’s love of gardening. The motto below the shield, “Make All Things New” is from the Book of Revelation, which signifies God’s power to completely transform and renew everything.
