Marshall Rosenberg was confronted daily with various forms of violence, growing up in the inner city of Detroit, Michigan. Wanting to explore the causes of violence and what could be done to reduce violence, he chose to study clinical psychology and received his Ph.D. in Clinical Psychology from the University of Wisconsin in 1961. Nonviolent Communication training evolved from Dr. Rosenberg’s quest to find a way of rapidly disseminating much needed peacemaking skills. The Center for Nonviolent Communication (CNVC) emerged out of work he was doing with civil rights activists in the early 1960's. During this period he also mediated between rioting students and college administrators and worked to peacefully desegregate public schools in long-segregated regions. Even after his passing in 2015, CNVC continues to be an international nonprofit peacemaking organization devoted to supporting the spread of Nonviolent Communication around the world.
