Christien Slotboom - Vreugdenhil

Chairwoman, Volunteer

Since 2017, I have been involved with True Grasses through contact with Anna Ruth through the primary school where our daughters became friends and we subsequently did too. After being active for income through the bike ride and the Christmas pieces, I now want to expand my commitment in the board of True Grasses. In doing so, I also want to be the link to Word of Hope, a cooperation partner of TrueGrasses in Tanzania. My sister and her friend Neema (Grace) Muhone have founded Word of Hope in another area in Tanzania; they provide tutoring (primary school level), Bible education and help with basic needs. From my background as a missionary daughter in Indonesia, with brothers and sisters in missionary and development work around the world, it has been in my heart to work for people less fortunate than us, especially children; because children are the future!

Janske serves on the Board of Directors of True Grasses as Secretary General and handles all organisational correspondences. She is a social worker by profession. Her husband Harry serves as TG online market logistics person. They are great advocates and promoters of True Grasses work of girl child education.

Lucas Schipper

Treasurer, Volunteer

On 1 January 2018 Lucas became the treasurer of the foundation. In his daily life he is a financial employee, specialized in European Grants administrations. As a volunteer he is treasurer of his church, the EGA in Assen, and has done volunteer work at the Foundation Femina. He has decided to take part as a volunteer at True Grasses because the organization works appeals to him. The people there get the means to have something to be able to build up so that they become self-sufficient individuals.

Janita van der Vinne

Public Relations, Volunteer

My name is Janita van der Vinne. I live in Assen and work at an agricultural IT company. I met Anna Ruth at the school of our children and that is how I got involved in the True Grasses foundation. I am married to Arjan and we are blessed with three children. They ‘naturally’ have the opportunity to join quality education and to develop themselves in a country full of opportunities. This is why I am motivated to spend my time and offer my creativity to the growth of education in Tanzania. I will mainly focus on the PR: flyers, movies, lay-out of newsletters etc. Furthermore I will join and support the board and organize fundraising actions.


Erika Koorn

Girls sponsorship coordinator, Volunteer

I am Erika Koorn. I have a big heart for equality in the world. Equal opportunities for everyone is what I would really like to see. Unfortunately, this is not the case. That is why I would like to dedicate myself to doing what we can. I enjoy being able to support True Grasses with the qualities I have been given. In daily life I do the (client) administration for a care institution and I am the mother of 3 boys. In my spare time, I like to read and run and you can find me a lot in nature.
