Jutte van der Werff ten Bosch did most of her training as a medical doctor, her paediatric training including his PhD and her education as a paediatric oncologist in the university hospital of Brussels, part of the Flemish speaking university of Brussels.

Afterwards, she spent 3 years in the Leiden University Hospital in the Netherlands to become a peadiatric immunologist and learn more about stemcell transplantation. During this period, the euthanasia law had just been implemented in the Dutch health care system and Jutte had the opportunity to learn more about the Dutch approach to euthanasia in general.

Since 2008 she has been working as a paediatric oncologist in the same hospital where she was trained and became the head of that department in 2013. Although she works mostly in the clinics, Jutte focus is on rare immunedeficiencies such as Toll like receptor defects, infections in immunocompromised children, and quality of life including end of life care.
