STRATEGIC
DIRECTOR

“I am an agronomist who has learned about ‘living systems’ with biologists and farmers around the world. I believe that a living-systems approach is necessary to tackle the complex issues faced by humanity and that any person working to effect change is a leader: one who builds leadership skills by doing, throughout their whole life. With 4SD, I commit to fostering unusual connections between sectors and actors and to contribute to collective intelligence.”

“I am a public health doctor who is energized by synergy of systems that impact on sustainable development. I sense that living systems leadership has enormous potential when applied to these kinds of interconnected and complex challenges. My own work has focused on people’s food systems, nutrition and health, as well as nature-based solutions in climate action”

SYSTEMS CHANGE MENTOR

“I love nurturing connections: between people with diverse backgrounds, between our personal “inner” world and the world around us, between my heart, body and mind…”

“The onus is on us to craft a world in which less harm is done to so many who live here. Which requires us to make real changes – to what we value, to our thinking, to how we listen and discuss and to how we make decisions.”

“I am endlessly curious about how people might live more meaningful lives and enjoy continually exploring what enables this in global and national environments, public and private.”

“I enjoy building bridges among people and environments not used to working together by leading a hybrid career on citizen engagement at the nexus of public and private sectors”
