We are the Principal Sponsor of Manchester United with headquartered in Chicago, Aon Corporation is the leading provider of risk management services, insurance and reinsurance brokerage and human resources consulting and outsourcing. Aon Advantage Our key advantage is our broad view of two of the most important issues in our economy today: risk and people. With an employee base of 59,000 people working in over 500 offices in more than 120 countries, we can anticipate how changes in one sector impact another. Another advantage is our client focus: Every day our employees ask, “How can we help a client or how can we help a colleague help a client?” Because each of our client groups has unique needs, our professionals—coordinated by strategic account managers, or relationship managers—specialize by product, function and client industry. By truly listening to clients and working with them as a partner, we can best develop solutions that work seamlessly with their business. Only in this manner can we help them uncover risks and discover new opportunities to make their business more successful, now and into the future.
