Welcome to Mater Dei Parish!
 
It is often said one of the most important parts of the Catholic Church is the parish. 

Why? 

The parish impacts people’s lives. In the parish, we receive the Body and Blood of Christ, listen to the Word of God proclaimed, find forgiveness of our sins in Reconciliation, build and foster community, and discover ways to bring our faith to life. 

The parish is a living, breathing entity because in it, God interacts with His people. 

We invite you to be a part of this life-changing experience of Mater Dei Parish! We hope you will find warmth and hospitality here in a spiritually and emotionally nourishing environment. 

We invite you to share your time and talents, too, so our parish grow in love and service to each other and our Lord. 
 
Again, welcome to Mater Dei Parish! We are excited you have chosen to be a part of our family!
