Begin Your Journey
Let this be your first step.

How long is Mass?

Most weekend Masses last about 60 minutes. Our 7 AM Sunday Mass is a little shorter because there is no music. Our weekday masses last 20-40 minutes, with 30 minutes being the average.

What should I wear?

You’ll see everything from casual to dressy. Come as you are — you are welcome here. Whether you’re arriving from work, school, or the gym, we’re grateful you’ve come. We gather in the presence of the Lord, so we encourage modest and respectful attire, but what matters most is your presence in worship.

Do I have to be Catholic to attend?

No. Anyone is welcome to attend Mass. If you are not Catholic, we simply ask that you remain seated during Communion or come forward for a blessing with arms crossed over your chest.

Will I be singled out as a visitor?

No. While we love meeting new people, you won’t be asked to stand or introduce yourself publicly.

What about young children?

Children are always welcome at Mass — their presence is a gift to our parish. We have a cry room available for families who need a quieter space, and many parents also step into the gathering area just outside the church. Both areas provide audio of the Mass so you can continue to participate.

How do I become a parishioner?
