With a starting capital of seven pennies, so would the tradition, The Zonnehuis Assocation was founded on 24 May 1921. The association is committed to dignified care for vulnerable older people who are permanently dependent upon care. Values such as solidarity, acknowledgment, and community building play a leading role. Since June 21, 2012 The Zonnehuis Assocation and Leyden Academy work closely together on shared goals such as the ongoing improvement of education for (future) healthcare professionals, improving the image of elderly care and the application of scientific research. Per 8 november 2017, after 96 years, the association is converted into a foundation, named the Jo Fisher foundation.
