Head of UK & Ireland
 // . //  Our People // David Gillespie

Having worked for over 20 years in financial services and consulting, David brings a wealth of experience to his clients. But sometimes the most important contribution he makes is providing perspective, pragmatism, and a healthy dose of common sense. 

David Gillespie heads up Oliver Wyman’s businesses in the UK & Ireland and leads the Financial Services and Organisational Effectiveness practices in the region.

He works with a large team of partners and consultants advising banks on strategic, organisational, and regulatory challenges and opportunities. He’s an expert in bringing together people from diverse backgrounds with different ways of thinking to creativity solve clients’ toughest, most complex challenges.

Oliver Wyman’s global, multi-sector experience allows us to bring our UK clients the best insights and learnings from other industries and countries.


With changes in regulation, advances in technology, and an unsettled political climate, large companies turn to Oliver Wyman to prepare. David and the team help these organisations combine their hard-won benefits of scale with much faster adaptability and innovation, enabling them to be better prepared for an ongoing, unpredictable business environment. These efforts can involve developing fundamentally different operating models, new business ventures, and new ways of working.

Scaled agility is key for big organisations. Those that adapt and innovate at speed will be best placed to succeed.

As a returning Oliver Wyman alumnus, David also heads up alumni activities in the UK. He encourages fellow alumni to keep up with the firm’s latest news, publications, and events via oliverwymanconnect.com.
