The soon-to-be installed bishop of the Phoenix Diocese, John Dolan, speaks at an introductory news conference June 10, 2022, while his predecessor, outgoing Bishop Thomas Olmsted, looks on.

The Roman Catholic Diocese of Phoenix has a new leader. Bishop John P. Dolan was most recently an auxiliary bishop with the San Diego diocese.

Pope Francis appointed Dolan to replace Bishop Thomas Olmstead, who retired on his 75th birthday in January. A Mass to install the new bishop was held Tuesday at St. Thomas Aquinas Catholic Church in Avondale.

“As we begin our journey together and as we reflect on our readings today, may I offer three proposals: simply, be good, be loved and be blessed,” Dolan said at the Mass.

Dolan is 60 years old. He is the fifth bishop of the Diocese of Phoenix, which serves about 1.1 million Catholics and covers about half of Arizona.
