What visitors say about St. Denis
Visitors appreciate the consistent access to the Sacrament of Reconciliation, with daily confessions offered Monday through Saturday.
The priests are highly regarded; Father John is noted for his detail-oriented approach and positive vision, while Father Dennis offers a warm, calming presence and remembers regular attendees.
The music ministry enhances worship, with an excellent choir at the Sunday 11:00 AM Mass and a skilled, spiritually moving Young Adult choir at the 5:30 PM Mass.
The church is known for its very welcoming atmosphere and is conducive to contemplative worship, featuring beautiful architecture and excellent acoustics that keep the interior quiet even during Mass.
