Karen Spencer, Founder & CEO

Karen Spencer founded Whole Child International in 2004 with the aim of improving the quality of care for vulnerable children worldwide. Targeting the largely overlooked emotional needs of society’s most at-risk children, Whole Child’s cost-effective, sustainable, and replicable program provides them with the tools they need to become productive members of society. As Founder and CEO of the organization, Karen leads an international team of trainers, researchers, and other staff to change systems of care, to advocate and influence policy, and to conduct related research. Whole Child programs are currently being brought to scale with funding from the Korean government through the Inter-American Development Bank and other donors. On February 20-21, 2010, His Holiness the 14th Dalai Lama came especially to lend his personal support to Whole Child at the launch of its global initiative to raise awareness of the plight of institutionalized children. During his two days supporting Whole Child, His Holiness participated in discussions with philanthropists, academics, government officials, and the public on how best to meet the needs of the most vulnerable children. Karen is co-author of articles published in the peer-reviewed Infant Journal of Mental Health, and Perspectives in Infant Mental Health, contributing important insights and realistic solutions to the public debate. In September 2015, she was elected an Ashoka Fellow for her innovative work as a social entrepreneur by the Ashoka Foundation, which honored her for identifying and filling a gap in care for orphans and vulnerable children. In 2016 she was made a Fellow at the University of Northampton in the United Kingdom.
