Harold Clarke has done something rare: embedded dialogue throughout not one but three state correctional systems. As Director of the Nebraska Department of Correctional Services, Commissioner of the Massachusetts Department of Corrections, and Director of the Virginia Department of Corrections, he has proven that dialogue can become central to how large, complex institutions operate. The Virginia transformation is particularly well documented: from 24 trained practitioners in 2010 to over 275, involving 13,000 staff and 105,000 people under supervision. In this participative webinar, cohosts Nancy Dixon and Linda Ellinor interview Clarke about how he achieved this feat repeatedly. The session moves beyond Virginia's specific story to explore Clarke's approach to organisational change through dialogue. For practitioners seeking to scale dialogue beyond individual sessions into systemic transformation, Clarke offers direct insight from decades of leadership in challenging environments.
