What if the reason your culture isn’t shifting… isn’t your people?

For many HR leaders, the pressure is familiar. You hire thoughtfully. You invest in development. You talk about inclusion. And yet, something still doesn’t move.

Because the issue isn’t just who is in the organization. It’s what they move through once they’re there.

In this episode, Mark Edgar sits down with Celeste Warren to unpack a more pragmatic, and more demanding, view of diversity, equity and inclusion. One that moves beyond representation and into the systems that shape access, opportunity, and performance.

They explore why so many DEI efforts fail to create real change, how the role of the Chief Diversity Officer has evolved through a decade of volatility, and what it actually takes to build environments where people can thrive.

This is not a conversation about optics or ideology. It’s about how organizations work, who they work for, and what leaders need to redesign if they want performance to be sustainable.

If you’re leading through complexity, trying to balance business outcomes with human realities, this episode will challenge how you think about both.
