Who we are

Katarina & Klaus-Dieter Gens

Two voices, one stance. We have lived and worked in a 'nonviolent' relationship for over twenty years, and have helped carry Nonviolent Communication into the German-speaking world since the 1990s.

Together — and each with our own voice. Below, two portraits: Klaus-Dieter, whose meeting with Marshall Rosenberg helped shape the story of NVC in Germany, and Katarina, who carries the active teaching today.

Klaus-Dieter Gens

Born 1950 in Wolfenbüttel, living in Berlin and the Havelland since 1969. I share a 'nonviolent' relationship with Katarina Gens — my partner, and since 2009 my wife.

I first met Marshall Rosenberg in Berlin in 1993. That meeting changed everything. From 1999 to 2009 I was a CNVC-certified trainer; for personal reasons I did not renew the certification. The German Professional Association for Nonviolent Communication later made me an honorary member.

For more than a decade I volunteered as Marshall's coordinator for Northern and Eastern Germany. I founded and chaired the former Centre for Nonviolent Communication Berlin, trained trainers in Berlin, Frankfurt, Hamburg, Kassel and Kiel, and led countless seminars at home and abroad.

Today I no longer work regularly as a trainer — I sometimes accept invitations as a guest trainer. I am a father, a partner, an Aries, curious, impatient, easily enthused, persistent, gentle, reconciling, eccentric, an inventor, a tinkerer. I drive an electric car, own a solar system and a heat pump, and am a firm believer in the energy transition. And, in the best NVC tradition of saying what one is not: I am not musical, not a smoker, not a dancer.

Born 1965, mother of two daughters, married to Klaus-Dieter since 2009. I live and work in the Havelland — and travel to wherever people wish to learn how to truly meet one another.

Since 2000, Nonviolent Communication has been my daily practice. From 2004 to 2008 I was a CNVC-certified trainer. I served as managing director of the former Centre for Nonviolent Communication Berlin and have led countless seminars, in-house trainings and introductory events over the past two decades.

Since 2012, together with my friend and favourite colleague Annette Del Olmo, I have carried the ongoing training work — practice seminars, foundational programmes, and the annual five-day SFBB further-education seminars.
