CEO Greg Case has passion for Aon. He cares for the colleagues and truly feels that Aon is leading the way across Risk and Human Capital. They are making investments into people that will allow growth, increasing client and shareholder value. I have always felt honored to work with some of the best and brightest in the industry.
