Why Organizations Struggle

Most organizations don’t struggle because they lack ideas. They struggle because decisions are fragmented, conversations stay superficial, and change doesn’t translate into action.

Serious Change® exists to close that gap.

We design executive decision-making, alignment, and change processes that work in real business contexts—using LEGO® SERIOUS PLAY® and experiential methodologies as sophisticated languages for critical thinking, not as superficial exercises.

How We Work

The Intersection of Strategy, Systems, and Human Behavior

Our proprietary framework bridges the gap between abstract corporate strategy and ground-level execution. We combine:

LEGO SERIOUS PLAY

We use the methodology not as a creativity tool, but as a rigorous language for thinking that makes hidden mental models visible and surfaces unstated operational assumptions.

Systems Thinking

We diagnose structural friction to understand organizational complexity and interdependencies, ensuring we address the system design rather than blaming individuals.

Change Design

We intentionally design executive conversations to translate collective insights into binding decisions and disciplined execution.

The result isn’t just better workshops. It’s better strategic outcomes.

Testimonials

I have worked with Gloria on a number of occasions... Gloria never ceases to impress me; she has the energy, the smartness, and the commitment to develop and follow through on business ideas and activities. She combines focus, enthusiasm, and integrity. The first two qualities make it a joy to work with her when I am in Mexico City; the latter is absolutely essential when collaborating across the Atlantic. Undoubtedly she is as good a consultant as she is a business partner.

Per Kristiansen, co-Founder and board member at Association of Master Trainers

I recently took part in Michel's LEGO SERIOUS PLAY methods facilitator training and highly recommend his training workshops. Packed full of learning, intensive and very enjoyable, the workshops not only provided a very thorough grounding in LSP, but watching Michel deliver the workshops over 4 days also provided lots of food for thought about the art of facilitation. Michel clearly puts a great deal of thought and care into his training workshops.

Stephanie Wheeler, leadership, personal development and systemic team coach & Award-winning Author

Working with Matthias is always a great pleasure and, without exaggeration, a true enrichment. Versed in LEGO® SERIOUS PLAY®, he has my unconditional recommendation for serious interventions—especially when it comes to clean assignment clarification and the thoughtful design of an agenda consistently tailored to the core question. LEGO® SERIOUS PLAY® is 'hard fun,' as the grandfather of the method says. Matthias can do both: invest a tremendous amount of experience and knowledge into the serious preparation of workshops, while steering them with warm-hearted dedication and consistent focus.
