I was diagnosed with vitiligo when I was 3 and I have been a member of the association since 1996.

This created the need to become more involved with When I read that there was a need for board members, that was reason for me to talk to the chairman.

 Marianne van Ooijen Secretary 

 Marianne (1956) lives in Roermond and works as an official secretary for works councils in the healthcare and municipal sector until July 1, 2023.

She does not have vitiligo herself, but her husband and (now deceased) father do have vitiligo.
There is therefore a lot of interest in possible remedies, especially with regard to the two now adult sons, who do not (yet) have vitiligo.
With my retirement in sight and already looking for an interesting alternative activity, the vacancy for secretary of the Vitiligo Association came my way just in time.
As secretary, I support the board in the broadest sense of the word.
