St. Michael Academy opened in September 1913, under the direction of the Dominican Sisters of San Rafael. Since its beginning, St. Michael School has been an integral part of St. Michael Parish. From the founding pastor, Father Patrick Power, to the present pastor, the school has been supported by the parish as an important part of the teaching ministry of the Catholic Church.

The original facility contained classrooms, living quarters for the sisters, and living spaces for a few young girls who boarded during the week and returned to their ranch families on the weekends. Subsequently, two classroom buildings were added to provide homeroom classrooms for students in grades one through eight. The original building became St. Michael Education Center and provided space for Faith Formation as well as extra classrooms, a school library, a technology lab, and administration offices. In September 1988, a kindergarten was opened. In 2003-2004, a new Education Center was built and the original facility was demolished. Over the course of 2011-2015, a technology program was implemented with strong infrastructure, iPad’s, Macbooks, and 1:1 devices in the middle school. In 2015, a Transitional Kindergarten, K-8 Spanish program and instrumental music (recorders) were established.
