Doreen was inspired in 1996 to join UNICEF, an organization which is mandated to address the development and protection of the world’s children. In the 24 years with UNICEF and through the senior leadership positions she held in Zambia, Botswana, Nigeria, USA, Denmark, Jordan and Uganda she developed a deep commitment for issues related to children, especially the most vulnerable. The work gave her first-hand experience of what it takes to deliver high impact results for children in different contexts at national, regional and global levels.
Doreen retired from UNICEF in August 2020 having served as UNICEF Representative in Botswana and Uganda; UNICEF Deputy Regional Director for the Middle East and northern Africa; having managed in collaboration with the Director and two other Deputy Directors over $3.4 billion annually at the UNICEF supply Division in Copenhagen, Denmark as Deputy Director Programmes; known for shaping how UNICEF engaged with countries on HIV/AIDS programming - most notably the scaling up of Prevention of Mother to Child transmission of HIV programmes. Additionally, she also led work on; Innovation, Innovative Financing, and helped address humanitarian action in Middle East and North Africa as well as in Uganda.
She is honoured to be part of the UK Lumos trustee board.
