Karen Spencer, Founder & CEO

Karen Spencer founded Whole Child International in 2004 when, as a single mother of two, she discovered an absence of services to address the social-emotional well-being of children living in orphanages. For the past 15 years, she has led an international team to improve systems of care, advocate and influence policy, and conduct related research. She has provided the vision and strategic direction for the organization’s growth, with a passion for systems change, sustainability, scalability, research, and third-party evaluation. The organization’s scope has expanded to reach an even broader group of vulnerable children, while retaining the original focus on emotional well-being. She is co-author of articles published in the peer-reviewed Infant Mental Health Journal and Perspectives in Infant Mental Health, contributing important insights and realistic solutions to the public debate. In 2010, His Holiness the 14th Dalai Lama came to Los Angeles, especially to lend his personal support to Whole Child. In 2015, she was elected an Ashoka Fellow 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. In 2017, People Magazine named her one of “25 Women Changing the World.”
