Aon is a global professional services firm that provides a wide range of risk, reinsurance, retirement, and health solutions. With more than 50,000 employees in 120 countries, the company supports customers worldwide by using propriety data and analytics to deliver insights that improve performance.
Aon’s commercial risk solutions offer risk advisory, risk transfer, and structured solutions that help business customers better identify, quantify, and manage risk exposure. Meanwhile, the company’s reinsurance solutions provide risk transfer, claims advocacy, and capital management solutions to help insurers and reinsurers reduce volatility and make their business resilient.

Meanwhile, its health solutions offer consulting, global benefits, and exchange solutions that help customers mitigate rising health care costs and improve employee health and wellbeing.
Aon’s roots can be traced to the integration of Ryan Insurance Group and Combined International Corporation in 1982. Throughout the 1980s and 1990s, the company expanded globally through organic growth and acquisitions.
The firm has been able to acquire some of the most well-known companies in the insurance and consulting industries – including Hudig-Langeveldt; Rollins Burdick Hunter; Reinsurance Agency; Miller, Mason, & Dickenson; Alexander & Alexander; and Benfield.
Aon aims to be the most responsive, client-focused insurance and consulting services firm in the world.
Case is the CEO and a board member of Aon plc. He achieved an MBA from Harvard Business School and graduated summa cum laude from Kansas State University. Before joining Aon, he led the global insurance and financial services practice of international management consultant McKinsey & Company. He also worked with the investment banking firm Piper, Jaffray, & Hopwood and the Federal Reserve Bank.
Aside from being a member of Aon’s board of directors, he also serves on the boards of Ann & Robert H. Lurie Children’s Hospital, CEOs Against Cancer, Discover Financial Services, Field Museum of Natural History, and St. John’s University School of Risk Management.
Aon strives to make a meaningful difference for clients and communities around the world by focusing on risk, retirement, and health. It has scored 100 from the Human Rights Campaign for 13 consecutive years and has provided $1.4 billion in disaster relief, the largest ever earthquake catastrophe bond that aims to help countries recover quicker from devastating earthquakes. It has also offered $120 million philanthropic funding since 2009 and achieved a 60% reduction in greenhouse gas emissions since 2015.
In 2019, the company developed innovative approaches to help people impacted by earthquakes in Latin America through quick reconstruction. Its apprenticeship program also gives participants promising careers and the opportunity to contribute not only to the company but also its clients.
