Staff members


Nathalie Martens-Jacquet – Managing Director 100%

« I want to do everything I can to make a seriously ill child smile and give him or her the strength to continue the fight. This is my goal in working for Make-A-Wish. Giving meaning to my activity is of great importance to me.»

Thanks to her previous professional experience, whether in international NGOs/institutions, a public administration or a medical foundation, Nathalie can put her skills to good use for this noble cause. Her different trainings, but above all her commitment and dedication, allow her to carry out these projects that are close to her heart.


Nathalie NnadyWish Granting Coordinator 80%

Since I started working at Make-A-Wish as Wish coordinator, I have had the privilege of seeing many children living with critical illness and their families smile again.

The power of a wish is so wonderful that the joy and happiness seen in our children and their loved ones becomes contagious. Together with wonderful volunteers and our generous partners and all the people that help us turn our children dreams into reality, I am happy to contribute, in my own modest way, in the beautiful achievement of Make-A-Wish.

From working a stand selling roses, to preparing a wish child’s itinerary to accompanying a family on a wish – in order to support the granting of magical wishes – volunteering at Make-A-Wish has been the most enriching experience of my life.

Board members (on a voluntary basis)


Jean-Pierre Boissonnas President

I have had the great pleasure of granting wishes to seriously ill children for many years and have decided to continue this commitment by joining the Board.

My career in the world of finance and my ability to activate an important network allow me to use these skills for the benefit of this wonderful foundation that is Make-A-Wish Switzerland.


Anne Empain Vice-President

I had the privilege to be invited to join the Board of Make-A-Wish in 2020. I was thrilled to join such a tremendously meaningful charitable organisation. A universal cause that we all care about – bringing happiness to a ill child and his family. The team is amazing, experienced and fully committed.

As a mother of 2 boys, one disabled, I am fully convinced that every grape of happy moment is energising for the whole family. I am committed to contribute to the mission of Make-A-Wish and put my expertise as international lawyer, perseverant problem solver and enthusiast of life to serve the children and their families.

Nicolas Müller Co-founder and Member

Make-A-Wish was a crazy dream and a shared ambition with my wife Sophia Ansar-Müller and Christina Firmenich. We wanted to help and give moral support to seriously ill children in Switzerland and Liechtenstein. By fulfilling a child’s dearest wish, the impossible becomes reality, including the possibility of a cure. Almost twenty years later, the Foundation is now recognized throughout Switzerland and Liechtenstein, thanks to the quality of the work done over the years by our volunteers, employees and members of the Foundation Board.


Christina FirmenichCo-founder and Member

When a child is able to fulfil a dream, they are amazed. They experience intense joy and create a memory that can stay with them through difficult times. Make-A-Wish does more than make wishes come true, it brings happiness and makes the impossible possible: the dream becomes reality!

My involvement and dedication since the creation of Make-A-Wish Switzerland have always been motivated by wanting to give back a smile, strength and hope to each child and to each accompanying family. Doing good makes me feel good.


Filippo DonatiMember

Make-A-Wish and I share the view that granting the wishes of seriously ill children is right and justified so that the child feels better psychologically. In my forty years of experience as a doctor, I have seen how important the well-being of the child and the support of the family are for the success of the treatment. A happy child, who has been able to realise his or her dream, is more tolerant of the side effects of the therapy (allowing the dosage and duration of the therapy to be increased) and is more tolerant of pain (allowing painkillers to be reduced).

I am very pleased and honoured to have recently been elected to the Make-A-Wish Foundation Board and I am committed to making sure that as many seriously ill children as possible get a wish. Furthermore, I am very happy to put my forty years of professional experience, my privileged relations in the German and Italian speaking part of Switzerland and my time at the service of the children, their families and Make-A-Wish.

Irene Sturdza Member

When I joined Make-A-Wish many years ago, I discovered the world of wish children, their families and children’s hospitals as well as how much, with an open heart, we can offer them but also receive from them. It has been a very meaningful personal journey.

I truly believe in volunteerism and supporting our most vulnerable fellow human beings, especially when it comes to children. I will continue, through my commitment, experience and know-how, to strive toward making a difference in their lives.
