Welcome to St. Nicholas Parish of O'Fallon, Illinois

St. Nicholas is a Roman Catholic Community formed in 1982. We number approximately 1400 households. We are committed to good liturgy, solid educational opportunities for all ages, and variety of ways in which we can be of service to each other and the community around us. We have a Catholic school (K-8) as well as a Parish School of Religion.  We now offer a wide variety of programs to help us each grow in our spirituality.  We recently opened our new campus, which features the Good Shepherd Center and the St. Nicholas Center.


Our church, the worship center, is the heart of our pilgrim journey, deepening our relationship with God.  We come together as a Roman Catholic community to celebrate the Liturgy of the Word and the Liturgy of the Eucharist enriched by meaningful homilies and a strong music ministry.  On weekdays, we gather for daily Mass in the intimate setting of Mary's Chapel.

The Good Shepherd Center provides a place for spiritual growth.  Through diverse meaningful programs and activities, we provide opportunities for personal growth, healing grace and peace.  We endeavor to create an atmosphere of hospitality and openess, welcoming those who gather to become closer to God.  Our chapel provides an environment of solace for prayer and reflection for all people seeking healing, wholeness and holiness in their lives.  The Good Shepherd Center is ecumenical and we welcome women and men of all faiths to visit and participate.


The St. Nicholas Center offers activities and events in a safe and wholesome environment that will physically, socially and spiritually strengthen individuals, families and the greater community.  The Center includes a Catholic preschool program for children ages three to five years old.  The Youth Ministry room provides a safe and nurturing place for teens to develop and strengthen their own relationship with Jesus and one another.  Our multi-purpose room is designed to provide indoor sports programs for youth through adults.


You are welcome to join us for prayer and in our search for ways to deepen our knowledge of God, celebrate His presence, and to join Him in service to our sisters and brothers.
