On May 26, 2011, Pope Benedict XVI named Msgr.
Robert Gruss as the Bishop of Rapid City.
He had served as the cathedral's rector and the parish pastor since 2010.
Gruss was the third rector/pastor to be named a bishop.

Bracke-Hayes-Miller-Mahon Architects (BHMM) of Davenport began working with the parish in 2012 to develop a plan to update the parish facilities.
A new handicap-accessible entrance on the east side of the cathedral was completed in January 2013.
In September 2016 construction began on the new hall immediately behind the cathedral.
It includes a gathering space, restrooms, a handicap-accessible entrance on the west side, a reception hall, and classrooms.
Mark Miller was the principal architect and Swanson Construction of Bettendorf was the contractor.
The hall was dedicated by Bishop Thomas Zinkula on November 19, 2017.
It was named for parishioners Weir and Pat Sears who gave the first $1 million for the $7 million project.
The gathering space was named in honor of Antoine and Marguerite LeClaire.
A new parking lot completed the project.

A tornado struck Davenport on October 6, 2016.
It did some damage to the cathedral and the rectory.
They were repaired, along with several other Catholic churches in the city, in the summer of 2017.
The original iron cross was replaced by a new aluminum, 24-karat, gold leaf cross.
The new cross was replicated from the original by a company in Kentucky.
A new carillon was added to the tower at this time.
The tower's original bell, cast for St. Margaret's in 1856, was removed, cleaned, and placed in front of the new hall's porte-cochere.
