Eric Andersen is named president of Aon, reporting to Greg Case, the firm's CEO, as Aon continues to accelerate execution on its Aon United Blueprint.


Andersen will lead an internal and external search to appoint regional CEOs who will be accountable for going to market as one, fully-integrated firm in each of its four regions – North America, Latin America, EMEA and Asia Pacific. Regional leadership teams will work across solution lines to ensure the best of the firm reaches clients and will collaborate with global solution line leaders to set the firm's enterprise-wide solution development priorities.


Michael O'Connor has decided to pursue new opportunities after a highly accomplished 12-year career with the firm. Andersen and O'Connor previously served as Aon Co-Presidents since May 2018.


The shift to a fully integrated model is consistent with Aon's emphasis on delivering the best of the firm to clients and a natural next step in its decade-long evolution into a leading global professional services firm. Previous structural changes, including the adoption of a single P&L structure, the move to a single Aon brand and the creation of a single operating committee laid the groundwork for this important step and remain critical going forward.


"Our firm has made tremendous progress in our Aon United journey, but there is still so much we can and will accomplish together," said Aon CEO Greg Case.


"Eric is a true believer in the power of Aon United and passionate about the value it creates for clients. His leadership will be critical in fulfilling the potential of one firm." Andersen, 55, has served in several important leadership positions throughout his 22-year career at Aon, including as CEO of Aon Benfield and prior to that as CEO of Aon Risk Solutions Americas. 


In addition, Aon announced that John Bruno will take on the additional role of Chief Operating Officer of Aon, reporting to Case. In that capacity, he will continue to lead development of the firm's Aon Business Services platform. Bruno, 54, will also continue as CEO of Data & Analytic Services and add the firm's technology-enabled Affinity offerings to that portfolio.


"We will continue to accelerate the application of new technologies to drive growth and make it easier for our colleagues to help clients make better decisions," Case said.


All the changes announced will be effective March 1


Most recently, Aon has entered a new phase of its Aon United growth strategy with the rollout of a single colleague mission called the Aon Impact Model, the scaling of its Delivering Aon United client value and sales effectiveness program, the development of the Aon Business Services platform to improve delivery of middle- and back-office client services and the formation of the firm's New Ventures Group to drive innovation at scale and expand its addressable market.


All these components are captured in the Aon United Blueprint, which enables Aon to maximize colleague opportunity and client value while driving sustainable growth with increased operating leverage.
