Get to Know the Parish

Then, the first Sunday every month, please plan on joining our wonderful Welcoming Team in the front of church after the 10:00am or Noon Masses for a brief tour of our Church and facilities. The tour will end in our parish center where we will join our Hospitality Sunday folks for coffee, donuts and more! We'll also answer any other questions your family might have about how we function as a parish and how we live our mission: 
May you find Christ here… may you find Christ to the world!
