The association aims to offer its members and all residents of the city of Aarau care and support in cases of illness, disability, and convalescence, childbirth, and old age at affordable costs. The association may also provide services that are not reimbursed by health insurance and/or the public sector and must be paid for by the customers themselves. Instead of providing care and support services itself, the association may become a member of an intercommunal institution that offers similar services. On this occasion, it may transfer its operations or parts thereof to the intercommunal institution. The board of directors is responsible for implementation.
