Pledged over 5 years for the Called to Renew Campaign.

Our Parish Receives


To renew our parish and strengthen ministries.

Parish Needs


It is time for us to restore some of the beauty and luster to our church with new flooring, painting, and lighting. With Called to Renew funds, we will renovate the men’s and women’s restrooms in the vestibule and replace the carpeting throughout the church with flooring that is more durable and easier to maintain, and, if necessary, install additional acoustic panels on the walls. We also will paint the interior walls, ceilings, and interior doors of the church. In addition, we will repaint the exterior of the church, and refinish and repair the exterior doors, including repairing the large wooden doors that are cracking. The marble tiles throughout the church will be thoroughly cleaned and polished. The broken marble tiles will be replaced or repaired, the grouting cleaned, and, where necessary, replaced. Lastly, we will repair the kneelers and modernize the HVAC system to be more energy efficient.

Outdoor Areas

The retaining walls, which are deteriorating and have unsightly bulges, will be repaired. We also will enhance the landscaping – e.g., by replacing the greenery on the hillsides with drought-resistant plants and by installing a new drought-friendly irrigation system. Lastly, we will create an outdoor play area for kids and an outdoor hang-out space for teens.

Pastoral Office Building

The receptionists’ office will be renovated; and the Pastoral Office’s second-floor wooden overhang will be refinished and repaired.

Potthoff Hall

We will replace the HVAC system with a modern, energy-efficient system and replace the leaky roof.


We will provide outdoor seating areas with tables and shade. The lighting and sound system will be upgraded so that people can regularly gather in the courtyard for fellowship. We also will replace the rotted trellises around the courtyard and create a mobile “St. Denis Café” where we can sell hot and cold foods.

A Bold Plan of Renewal

We — the Catholic faithful — are the agents of renewal for Church and society. I am grateful for this opportunity to walk alongside clergy and parishioners in strengthening our parishes and ministries, the heart of our Archdiocese.
