The process of Nonviolent Communication (NVC) was developed by the clinical psychologist Marshall Rosenberg in the late 60s. The name of this modality was born out of the civil rights movements and the Detroit race riots that Rosenberg experienced. The Centre for Nonviolent Communication (cnvc.org) supervises and accredits trainers, coaches and mediators. In the hands of a master, I have witnessed breath-taking transformations, particularly in the area of mourning and reconciliation.
Professional and personal challenges lead me to the work of Marshall Rosenberg. I experienced it as a paradigm shift in the way I related to others. Over the years it has been developed into a very visual and creative approach. The core principles can be learned quite quickly, it is theoretically straightforward and can shine a light on both intrapersonal and interpersonal conflicts in an efficient way.
I am delighted to be co-facilitating with Trond, who brings a breath of experience in the organisational and team setting. In this two day programme, you will experience Rosenberg’s process in an experiential way and we will explore the applications of this approach to your coaching and psychotherapy practice. We will work in small groups, full group, with demonstrations and plenty of opportunity to practice. The training will be delivered in a very visual, creative and playful way.
