The Association of Local Authority Risk Managers' (Alarm) newly appointed chief executive Sheila Boyce will take up her role in January.
Boyce, currently a manager with Aon Public Sector Consulting Group, was appointed to replace Liz Taylor, who is leaving Alarm to head a public risk services division for Marsh.
Alarm is the UK's biggest organisation dedicated to public sector risk management, with 1,200 members.
Boyce said she was delighted to join Alarm and was confident she could help it achieve its objectives.
"Alarm has grown and developed rapidly over the past two years, raising its profile and establishing itself as a key contributor to the successful management of risk in the public sector," she said.
"I'm keen to work with Alarm's chairman, council and members to enhance that position."
Boyce has experience as a risk and insurance manager with Wycombe District Council and HYPO Mortgage Services.
She is also an associate member of both the Institute of Risk Management and the Chartered Insurance Institute.
