Early MotherhouseThe Sisters of St. Mary of Oregon were founded by a few young women with a dream. Our community was founded in Sublimity, Oregon in 1886. The Sisters began teaching in the local parish almost immediately. In 1891, Archbishop William H. Gross asked the Sisters to serve at St. Mary’s Orphanage in Beaverton. In 1894, the Sisters began the construction of a Motherhouse in Beaverton. In 1905, the Sisters changed their name to the Sisters of St. Mary. We are known today as the Sisters of St. Mary of Oregon.

Our Campus Schools

Education on the campus of the Sisters began in 1903 and continues to this day. Valley Catholic School is Oregon’s only pre-K through grade 12 Catholic educational system. Additionally, our Sisters have taught in schools across Oregon and Washington.

  • In 1930, a new brick Motherhouse was erected. It also served as a school building.
  • By 1969, the dream of a separate high school building was realized.
  • In 1991, an early learning facility opened its doors. That year, our high school became coed and changed its name from St. Mary of the Valley High School to Valley Catholic. Several years later, all of our campus schools changed their names to Valley Catholic.
  • A new, LEED gold certified elementary and middle school building opened in 2006.
  • In 2013 and 2014, enhanced athletic facilities – including lighting, artificial turf, a grandstand and field house – were added to the campus.
  • A  two-story science building was dedicated in 2016. It features five state-of-the-art labs, a greenhouse and additional general use classrooms.


Recognizing the growing need for elder care, the Sisters established Maryville in 1963 and quickly developed a reputation for outstanding skilled nursing care. In 2011, Maryville opened a new residential care facility exclusively devoted to the care of those with Alzheimer’s and other dementias. In 2015, a new transitional care unit opened to meet the increasing regional need for short-term physical rehabilitation.
