Catalysts for Change

What does it look like to lead an organization you've spent nearly two decades growing inside of? In this episode of Catalysts for Change, host Adam Lister sits down with Stephanie Coleman, President and CEO of the Nashville Area Chamber of Commerce, for a candid conversation about stepping into the top seat and everything that comes with it.

Stephanie joined the Chamber in 2008 and served in six different roles before being named CEO in 2025. She opens up about the real shift in mindset that comes with moving from deputy to chief, from executing plans to casting vision,  and why leading at a sustainable pace matters just as much as leading with urgency.

Stephanie discusses the Chamber's Partnership 2030 economic development strategy and its three pillars: community vitality, mobility, and character, as well as bold goals, such as growing Chamber membership by 50% in five years. 

The conversation also gets personal. Stephanie reflects on the hardest leadership lesson she's learned, how she stays grounded outside the office, and what she wishes she had known in her first year as CEO. 

Thoughtful, honest, and full of practical wisdom, this episode is essential listening for anyone navigating a leadership transition or driving meaningful change in their community.

Season 3 of Catalysts for Change launches with a powerful conversation between Adam Lister and Nashville Sheriff Daron Hall, a leader who has spent more than two decades rethinking what public safety can look like.

Sheriff Hall shares the defining question that has guided his career: not who commits crimes - but why. That perspective has led him to challenge long-held assumptions about incarceration, mental health, and the role of the criminal justice system.

From his early fascination with criminology to his eye-opening experience representing the United States abroad, Hall reflects on the moment he realized the system wasn’t just imperfect, it was fundamentally misaligned. In many cases, he argues, jails have become the default solution for mental health crises, creating cycles that don’t address root causes.

The conversation explores how Hall helped lead a bold shift in Nashville: building a behavioral care center alongside the jail to divert individuals in crisis away from incarceration and toward treatment. Along the way, he shares hard-earned lessons about leadership, navigating politics, building unlikely partnerships, and why meaningful change often requires both strategy and courage.

This episode sets the tone for the season, highlighting leaders who are willing to question the system, rethink the problem, and take action to create lasting impact.

In this episode of Catalysts for Change, Adam Lister sits down with Beth Harwell, Tennessee’s first female Speaker of the House and one of the state’s most influential political leaders. Over three decades in public service, Harwell helped shape landmark policy on education, welfare reform, taxation, and public health—often bridging deep divides through civility and pragmatic compromise.

Harwell shares her journey from a young political science professor inspired by the Watergate hearings to becoming Speaker during one of Tennessee’s most transformative eras. She reflects on lessons learned from both sides of the aisle—why compromise isn’t weakness, how to lead in complex times, and why making people feel seen is the cornerstone of effective leadership.

From repealing the state’s inheritance tax and advancing Tennessee Promise to navigating fierce debates over charter schools and even wine in grocery stores, Harwell reveals what it really takes to move meaningful change through divided government.

This conversation is a study in humility, perseverance, and principled leadership—offering wisdom not just for public servants, but for anyone leading in high-stakes, high-pressure environments.
