Beyond Belonging

Why workplace mattering is the metric that actually drives productivity and happiness

Belonging gets all the attention — but belonging is passive. You can belong to a group and still feel invisible inside it. Mattering is different: it's the felt sense that your presence changes something. Drawing on Industrial-Organizational Psychology research and two decades building cultures from Zappos to the Fortune 500 boardroom, this talk makes the empirical case that organizations measuring belonging are asking the wrong question — and shows leaders exactly what to measure instead.

Culture as a Public-Health Intervention

Loneliness is now a clinical epidemic. Disengagement costs the global economy $8.8 trillion annually. And organizations — whether they know it or not — are one of the few remaining places where daily human connection still happens by design. What changes when leaders stop treating culture as a perk and start treating it as one of society's last available public-health infrastructures? This talk answers that question — and gives leaders a framework for acting on it.

A Tuesday Kind of Talk

The micro rituals, the quiet reach outs, the behind-the-scenes support that makes a person feel like they matter. Belonging and deep connection isn't built in the highlight reels. It's built in the quiet infrastructure of our ordinary lives, through small repeated acts of contact that accumulate long before anyone steps on a stage.

This talk explores why organizations that invest in creating micro-rituals of connection and support in the moments between milestones — build cultures where the big moments mean so much more. Drawing on behavioral science, IO Psychology research from Harvard, and the fieldwork behind The Tuesday Project, it's a case for the power of what happens in the in-between.
