Our Lady of the Sierra (OLS) Parish is comprised of the communities of Oakhurst, Bass Lake, and North Fork. The parish includes the outlying communities of Coarsegold, Yosemite Lakes Park, Ahwahnee, Wishon, and other areas. OLS is rooted in the Roman Catholic Church under the leadership of Pope Francis, and is shepherded by Bishop Joseph Brennan of the Diocese of Fresno. Her current pastor is Rev. Victor Hernando.

OLS had her humble beginnings on the shores of Bass Lake in 1939, when the little mission of St. Dominic Savio, the former Santa Teresita Campground of the Fresno Diocese, came into being. In 1960, the fledgling community of Catholic believers received a papal blessing to establish St. Dominic Savio as a mountain parish with St. Joseph as its mission church.

Thirty-two years later in 1994, parishioners began to build Our Lady of the Sierra Church in Oakhurst and completed its construction in 1999. That same year, the seat of the parish was transferred from Bass Lake to Oakhurst. Our Lady of the Sierra became the parish church and St. Dominic Savio and St. Joseph the Worker her mission churches. Since her formal establishment in 1961, Our Lady of the Sierra has been served by nine priests and seven bishops.
