Steffen Weiberle- Facilitator

Steffen was exposed to Marshall Rosenberg's material and NVC in early 2007 by participating in a self study group using the book "Nonviolent Communication" and the companion workshop. Both the book and the group were very eye opening and inspiring. Wanting to dig deeper, Steffen started looking for other ways to learn and experience NVC. In 2008, he started attending NYCNVC events and working with Thom Bond

Steffen has over four hundred hours of dedicated time learning, facilitating, co-facilitating, introducing, and sharing Compassionate Communication with individuals and groups new to NVC, and those familiar and wishing to practice. This includes six 9-week workshops he has facilitated in southern New Jersey since 2009, and groups he facilitates regularly to practice Compassion Communication.
