I have been coming here since 2016, and now I get to strengthen this special place from the inside as well. I have become a board member of Jan XVII, the foundation behind ZeeVELD, perhaps the most beautiful and vibrant retreat centre in the Netherlands.
A place where silence, nature and personal growth come together.
To me, retreats are the greatest gift you can give yourself. That is why, as a volunteer board member, I am happy to contribute to the continued existence and development of this place.
