For those working to reverse ecological crises and innovate solutions, the greatest untapped resource is a deep understanding of human behavior.

It is time to fully comprehend how people feel, experience, come to terms with, and act in our ecologically fragile world.

Knowing how people relate to change enables us to engage, mobilize, and inspire positive action.


Each one of us cares about our planet. However, it’s not always clear what to do about it.

Our need to understand human behavior at the deepest levels is no longer an option, when it comes to meeting our most urgent ecological challenges. Innovating solutions, crafting engagement strategies and designing astute messaging all require a fundamental fluency in how people not only think, but feel about our changing world.

She works with leaders in business, government, NGOs, and academia to develop innovative research, insightful strategies, and transformative learning programs to effectively engage stakeholders in responding to the most profound challenges of our time.
