Bishop John S. Siemianowski, welcome to Vicariate II!

As of March 1, 2025, we here in the second vicariate of the Archdiocese of Chicago have a new auxiliary bishop! John S. Siemianowski was ordained as a bishop by Cardinal Cupich at the Holy Name Cathedral on February 26. At the end of the liturgy, Bishop Siemianowski received his assignment to lead Vicariate II.

Bishop Siemianowski, 64, was ordained in 1989. He served as associate pastor of St. Francis de Sales, Lake Zurich; St. Mary, Buffalo Grove; and St. Elizabeth Seton, Orland Hills. He later served as pastor of St. Agnes, St. Paul, and St. Kieran parishes in Chicago Heights. In 2021, he was named pastor of St. Juliana Parish, where he continues to serve.

We would also like to congratulate our former Vicar General, Robert Casey, on his recent appointment as the Archbishop of Cincinnati.

Lord, we pray for Bishop Siemianowski and Archbishop Casey as they enter their new roles in your service!
