The IHM School Expansion Project
IHM School was founded in 1976 by Brother Hugh MacIsaac in a small ranch house for a few students. The original makeshift building has grown into the present campus through the efforts of Brothers and volunteers.
In the 1990s, the addition of a second and third floor enabled enrollment to grow to 120 students across grades 1-12. The completion of MacIsaac Hall in 2016 provided new classrooms for the high school and created additional space in the original building, which was soon fully utilized.
With the original property fully utilized, further expansion was only possible if additional land could be acquired. In 2018, 77 acres adjacent to the school became available, and through generous donations and successful fundraising, we were able to purchase the land. The Brothers collaborated with professionals to design an addition that harmonizes the styles of the existing building and MacIsaac Hall. After years of prayer, dedication, and fundraising, the stunning new building opened its doors in 2025 and is now fully operational.
Today, education faces a profound crisis, particularly for Catholic families seeking a school that mirrors the values taught at home. IHM stands firm in its Catholic mission, offering a truly authentic, faith-based education. We remain deeply grateful for all who have supported IHM’s growth and mission, trusting that God will bless those who have made this journey possible.
