Founding and Mission Era (1875–1972) Wasatch Academy was established on April 19, 1875, by the Reverend Duncan McMillan. McMillan, a Presbyterian minister, had originally come to the Sanpete Valley to recover his health. He was encouraged to start a school by the local Liberal Party and "apostate" members of
The Church of Jesus Christ of Latter-day Saints who sought an educational alternative to the dominant LDS culture of the time. The school opened in "Liberal Hall," a building that served as a schoolhouse, church, and community center. For nearly a century, the school operated as a mission school under the Presbyterian Board of Home Missions, educating a diverse population of local students, Native Americans, and boarding students from the intermountain region.
Independence and Modern Era (1972–present) In the early 1970s, the Presbyterian Church began divesting its mission schools. Facing potential closure, the school's administration and alumni purchased the campus in 1972, transitioning Wasatch Academy into an independent, non-profit institution. While it is no longer governed by the church, the school retains a historical "interfaith" tradition. In 2025, the school launched the "McMillan and Sanpete Scholars" programs and hosted a Sesquicentennial Gala to commemorate its 150th year. ==Academics==
