Jette is my village within the city. I've lived here for fifty years and know its parks, its habits, its faces. This is where I chose to teach — to share this ancient art in the community where I have my roots. In Jette, French and Dutch have naturally coexisted since time immemorial. My classes reflect that spirit: bilingual, open to both communities, because Qi Gong is precisely that art which transcends borders and builds connection.
​
My path in the energy arts began in 1988 with Aikido, which I practised for over twenty years — earning my black belt, and continuing beyond it. But the body has its limits, and I felt the need for a path that could be followed for an entire lifetime. Qi Gong became that path. Over the course of this practice, the study of heart coherence naturally enriched it: neuroscience meets age-old practices in a mutual enrichment. This convergence became the heart of my research, long before I began to teach. I cultivate patience and attention with my bonsai trees as well.
