Milliman is an independent actuarial and consulting firm founded in 1947 and owned and managed by its principals. For more than 75 years, it has advised clients across the public and private sectors - including insurers, healthcare organisations, employers, and governments - on questions involving risk, financial security, and population health. Its work spans healthcare, insurance, life sciences, employee benefits, financial services, and risk management, including longevity risk and climate and extreme weather risk.
The firm operates globally, with offices in major cities around the world. Its consulting practice combines actuarial science with advanced technology and analytics to address problems such as market volatility, rising healthcare costs, insufficient access to insurance, and the financial implications of an ageing population. Clients range from large commercial insurers and healthcare organisations to community-level bodies and national governments.
Milliman's principals are distinguished by their technical and business expertise. The firm's independence - it is not publicly traded and carries no external ownership - shapes how it positions its advice: as objective and grounded in professional rigour rather than product sales. Its stated mission is to protect the health and financial well-being of people everywhere.
