Our history

A History Of Forward Thinking

Our eyes have always been
trained on the future.

That's illustrated by the series of mergers, acquisitions, and geographic expansions that dot our timeline and have shaped our firm. From developing our annual State of the Financial Services Industry report to creating a long-range vision for New York City as the world's leading media capital, it's forward thinking that allows us to tackle current issues, understand their long-term implications, and prepare our clients to harness the power of all that lies ahead.

    (From left) Oliver Wyman founders Alex Oliver, Chuck Bralver and Bill Wyman.

    We were looking to start a
    firm that was less hierarchical and more collaborative,
    a firm where people could rise in the organization with a speed that matched their accomplishments. We were also seeking to build a business culture that
    was intellectually and philosophically converged. And we wanted to have
    more fun along the way.

    Oliver, Wyman & Company founded in New York

    The Financial Services industry had just been deregulated, and many of the major players were truly unaware of the economics of their own businesses. Oliver Wyman saw this as a prime opportunity to help major players gain a measure of clarity about their businesses, products, and customer groups and then help them set far-reaching strategies.
