The foundation's purpose is to operate the St. Otmar old-age and nursing home (located at Minervastrasse 8, 8032 Zurich, owned by the founder). The St. Otmar old-age and nursing home is run in the tradition of diaconal care with an ecumenical Christian attitude and is open to people of all denominations and worldviews. The management is not focused on profit, but on the well-being of the residents. The foundation has a non-profit character and does not pursue any commercial or self-help purposes. Any potential profit flows into the house's renovation fund.
