Parish Life at Immaculate Heart

Immaculate Heart is a vibrant parish community. We welcome all to participate in parish life, as it is a great way to get to know other members of our community and grow in faith. There are many activities and planned events that enable our parish family to thrive. We rely upon volunteers to facilitate our many offerings. First, since we are joined by the Holy Spirit and our shared Catholic Faith, we ask for your prayers. Second, we warmly invite you to attend any of the activities that interest you. Third, you are encouraged to help in keeping with your interests, talent and availability.
