St. Aloysius Retreat House is a house belonging to the Society of St. Pius X. On site is a priory, which is a religious house of common life for priests. These priests preach retreats and exercise their apostolate in the outlying regions.
The Society priests who reside here serve a community of faithful who attend Mass at the chapel of Our Lady of Perpetual Help located on our grounds.
The Retreat House has been in Los Gatos since the early 1990s, and preaches a variety of forms of Spiritual Retreats, most notably the Ignatian Retreats.
