Our story
Organizations need leaders and teams that can address what matters, navigate conflict constructively, and turn existing potential into performance. I founded 8C Consulting to help organizations understand what holds people and teams back and strengthen the leadership, relationships, and organizational conditions needed for sustainable results.
Today, we combine executive coaching, leadership team development, and cross-cultural expertise with approaches including Transactional Analysis, Nonviolent Communication, and Positive Intelligence®. In this way, we help leaders and organizations develop the capabilities needed to communicate openly, collaborate effectively, and perform sustainably.

“Avoided conversations create friction. Destructive conflict erodes trust. Both limit ownership, innovation, and performance.”
Over 25 years in corporate HR, leadership, and executive coaching — including as HR Director for General Motors Europe, where I led HR for a 3,000-employee division through major organizational change — I've seen talented people and capable teams held back by unproductive ways of communicating, leading, and navigating conflict. Since founding 8C Consulting in 2019, I've coached C-suite executives, General Managers, and senior leaders at organizations including BMW, Mercedes, Porsche, Henkel, and Würth, accumulating more than 4,000 hours of coaching, consulting, and facilitation.
When conflict is handled well, it becomes a competitive advantage and drives learning, innovation, stronger relationships, and sustainable performance.
Our mission is to develop leaders who create psychological safety, foster healthy conflict, and build organizational cultures where trust, ownership, and performance reinforce one another.

“The quality of relationships determines the quality of conversations—and ultimately the quality of results.”
As a specialist in human relationships and communication, and a certified Transactional Analysis Consultant, I've learned that team effectiveness depends on something that is often overlooked: our level of self-awareness and our capacity for empathy.
By combining the self-awareness fostered through Transactional Analysis with the non-judgmental and empathy-centered approach of Nonviolent Communication, we help individuals recognize the patterns that shape their interactions. This enables teams to communicate more empathically and consciously, build stronger relationships, and create healthier dynamics that support collaboration and performance.
