Kelly Grehan
Policy Manager, Revolving Doors

Kelly Grehan is a former Probation Officer and experienced criminal justice practitioner whose career has been defined by her commitment to improving outcomes for people with complex needs in the criminal justice system. Over nearly two decades in probation, she worked in multiple teams, including in Court and the substance misuse team. She then qualified as a Practice Tutor Assessor and trained and assessed trainee Probation Officers. Her frontline practice continues to shape her national policy and advocacy work.

Kelly is now Policy Manager Manager at Revolving Doors, the national charity dedicated to breaking the cycle of crisis and crime. She brings a rare combination of practitioner insight, policy expertise and lived‑experience leadership to her work, ensuring that the voices of people repeatedly drawn into the justice system inform national reform. She has led campaigns on the rise in recall, the decline in pre‑sentence reports, and the cultural challenges facing the Probation Service, securing significant engagement from parliamentarians, practitioners and the wider sector.

Before joining Revolving Doors, Kelly worked in Parliament, supporting Shadow Justice Ministers.

She is a member of the Vulnerability & Policing Futures Research Centre, contributing practitioner expertise to national research on policing, vulnerability and system reform.

Alongside her professional roles, Kelly is a committed advocate for women’s leadership and gender‑responsive justice. She is a member of the Fabian Women’s Network Executive Committee, where she leads work on criminal justice, domestic abuse and women’s safety, and regularly convenes cross‑sector events bringing together policymakers, practitioners and lived‑experience experts.

Kelly holds a BA (Hons) in Social Policy, a Diploma in Probation Studies, a Post Graduate qualifications in Counselling and is currently studying an MPA  in Social and Public

Her career reflects her enduring commitment to the values of probation: hope, professionalism, social justice and belief in people’s capacity to change. Her contribution to practice, policy and public understanding of probation makes her a valuable addition to the Probation Institute Fellowship.
