Immaculate Heart of Mary Church began humbly in 1945 when twenty-five faithful gathered to break ground under the guidance of Father William Pezold. From its early beginnings as a small mission parish of twenty families, the church quickly grew in both spirit and community strength. Over the decades, dedicated parishioners and clergy expanded the facilities, built sacred spaces such as the grotto honoring Our Lady of Fatima, and nurtured faith through education and fellowship. By 1956, the mission became a full parish, marking a new chapter of growth that included a rectory, parish school programs, and the introduction of cherished parish dinners that became a cornerstone of fellowship and support.

Through the leadership of devoted pastors and the generosity of its members, the parish flourished, culminating in the dedication of a new church in 2003, capable of welcoming hundreds of worshippers. The completion of the Grand Hall in 2009, later named the Father Stoltz Grand Hall, stands as a testament to the enduring stewardship and unity of the parish family. Today, Immaculate Heart of Mary Church remains a vibrant and welcoming community, grounded in hospitality, liturgy, and education. Guided by the faith and vision of generations past, the parish continues to grow as a place of worship, service, and grace, ever committed to glorifying God and serving others in His name.
