Become a member of Hoffnungsbaum e.V. and support the work of the association.



Most members of our association are parents of affected children or other close relatives of affected relatives. In addition, there are people interested in the topic of NBIA because they have friends with affected children or because they are professionally involved with NBIA disorders. Member of the association Hoffnungsbaum e.V. can become a member of the association Association goals and who wants to support the work of the association actively or only passively by his membership fee. The members of the association will be informed about research results and other news in the field of NBIA and about the activities of the association. Of course, every member can also participate in the activities of the association. Our goal is to reach as many interested people as possible through membership and to win them over to the goals of the association in order to plant as many "trees of hope" as possible for the future of people affected by the disease.
