The story begins with Sister Annette Relf, the first Episcopal deaconess in Minnesota. Her dream was to create an orphanage and she did. She founded the Sheltering Arms orphanage in 1882. In 1900, Sheltering Arms received land on the west bank of the Mississippi from the estate of Richard Martin and in 1910, the brick orphanage building was built. The stone chapel, still in use today, was built in 1922. The main building continued to operate as an orphanage until 1942, when it became the Sister Kenny Treatment Center for people with polio. In 1955, the building became a day school for children with developmental disabilities.
