The United States Province of the Company of Mary was formed from the Canadian Province in the 1950s. It is mainly confined to the Eastern States.
The Province has two retreat or pastoral centres, one at Bayshore, NY, and one at Litchfield, Ct, where there is also a Marian shrine, Lourdes in Litchfield. Another Marian shrine, Our Lady of the Island, is maintained at Eastport, Long Island, NY.
The members of the Province carry forward the mission of the Congregation through preaching (a mission team gives parish missions), the conducting of retreats, the pastoral care of visitors to the shrines, work in a number of parishes, and publishing.
The Province produces a review, "Queen Magazine", and publishes the works of St Louis Marie de Montfort and other books related to Montfortian spirituality, through Montfort Publications at Bayshore, NY. The Province is responsible for a small mission in Nicaragua.
