This 9-day immersion experience into Nonviolent Communication (NVC) will offer learning sessions, home groups, coaching and feedback from skilled trainers, and a community environment where you can learn and practice the key skills of NVC.

Our team of Certified Trainers will share both the core curriculum of NVC as developed by Dr. Marshall Rosenberg, as well as their own unique applications. We expect a group of approximately 60 to 80 people from different countries, cultural backgrounds, professions and walks of life.

People around the world are using Nonviolent Communication skills to transform conflict, create resiliency in their relationships, and build a world where everyone's needs matter and are met collaboratively.

We will create a dynamic learning laboratory that will show you how to create a more compassionate and peaceful culture in your life at home, at work, and in your community by learning how to:

  1. Speak from the heart

1. Personal and Professional Relationships

  • Increase connection and closeness with the people you love.
  • Speak in a way that inspires compassion and understanding.
  • Initiate difficult conversations with more ease and confidence.
  • Remain centered and peaceful when receiving difficult messages.
  • Express and receive anger fully, safely and respectfully... yet powerfully.
  • Resolve long-standing conflicts and heal painful relationships.
  • Parent children from the heart and move beyond power struggles into cooperation.
  • Translate criticism, judgments and blame into life-serving messages.


2. Inner Transformation

  • Shift patterns of thinking that lead to depression, guilt and shame and that perpetuate pain.
  • Transform anger into self-understanding, thereby increasing inner peace.
  • Enliven yourself by expressing and receiving gratitude.
  • Learn to embody unconditional love.

3. Contribution to others and Social Change

  • Share NVC in ways that transmit and model its power to transform and inspire others.
  • Create educational systems where students love learning and teachers love teaching.
  • Learn to engage in effective, lasting nonviolent social change in the tradition of Gandhi, Nelson Mandela, Desmond Tutu and Dr. Martin Luther King, Jr. 
  • Facilitate meetings and support group decision making in a power-sharing, collaborative, and consensus-based ways.
  • Support holistic and human-based workplaces
  • Engage with others at work and in the community to foster openness, trust and authenticity.
  • Support mutual understanding and connection when working in colonised countries.
  • Foster restoration and harmony by mediating conflicts and helping to resolve differences among others.

While we will prioritise these three areas in the curriculum, there is also room for co-creation. There will be opportunities for you to request specific topics and applications to support you in living and sharing NVC at work, home, and in the community as well as internally in how you relate to yourself.
