Matteson Mission School is supported by the Granheim Foundation, which is a non-profit organisation (org.nr. 960 801 105). The foundation is committed to providing facilities, whether by owning or renting, to Matteson Mission School or other projects that follow the guidelines given on education in the Bible and the books of Ellen White.
As classrooms connected to the school the Granheim Foundation also operates some services for the local community:
A composting plant with reception of branches from private gardens in the community. Over the years the foundation has developed an organic compost of high quality that is available for sale.
A lifestyle club called “Livsstilsklubben Mysen” that promotes healthful living.
According to the school program, each Matteson student invests 10 hours work per week for the Granheim Foundation as part of their compensation for their stay at the school.
