Our Team

  • George Halvorson, Founder, Institute for InterGroup Understanding

    George Halvorson

    George founded the Institute for InterGroup Understanding to help reduce InterGroup conflict and stress in America, and to offer advice to people who face InterGroup conflicts in other areas of the world. George served as chair of the First 5 Commission for Children and Families for the state of California, and he is the author of four books on intergroup understanding — one on early brain development in children, and seven on health care quality improvement and reform. George has served as CEO for multiple health care delivery systems and financing organizations for more than three decades.

    George has served on nearly 40 health care delivery and reform, and public policy related boards, commissions, and task forces — and has chaired nearly a dozen of them. He founded the Institute because he believes that issues of InterGroup Understanding will determine the future success (or failure) of our country. He wants to create a resource that will help InterGroup Peace become the culture, the shared commitment, and our functional future reality. George deeply believes we need to save every child, and that we need to collectively achieve the goals, and "do the right things at the right times" to save every child in order to give Peace a chance.
