Quentin set up Marble Brook because culture – accepted thinking, choices, and behaviours – makes or breaks a company’s ambitions to create value.
Make culture as an asset
Quentin works within FTSE, multinational, and medium-sized businesses to align strategy, leadership, and practice, and so turn culture into a unique asset.
With hands-on expertise in business, management, and complex systems, he stretches companies to find value within the trends that disrupt industries, brands, and careers.
A skilled facilitator, Quentin challenges executives to explore strategic questions that matter to the company and to themselves. With robust discussion he secures agreement on ways forward.
A critical friend, he builds trust and connects across functions and levels. He shapes dialogue with fresh ideas, helps answer thorny questions, and coaches managers to overcome resistance.
Coalface of leadership
Quentin knows what days are like at the coalface of leadership. As a Chief Operating Officer in banking, he led multidiscipline, client-facing teams of up to 130 people, with budgets over US$100m.
He also ran, across US$1bn businesses of more than 1,000 employees, culture initiatives to increase revenue, enhance service, and cut cost.
Outside the office
His MPhil in Innovation, Strategy and Organisation from Cambridge and MSc in International Management from London allow Quentin to grasp the hidden dynamics of performance.
During his first degree, he moved from Oxford to Asia and learned about culture the hard way. Proficient in Mandarin, Quentin has lived and worked in New York, Hong Kong, and Taipei.
I very much recommend Quentin’s thought leadership and his gift for uncovering new paths to engagement and best practice. He has an amazing way of shaping and framing ideas to enhance clarity of thinking and deliver robust outcomes. Quentin is a trusted authority in his field, and has the depth – of knowledge, perspective, and experience – that comes from helping senior teams and boards make the most of new opportunities.
Lloyds Banking Group
From day one Quentin showed a great appetite to really understand the two cultures and business objectives. He brought with him a vast amount of experience and techniques but was very open and flexible to suggestions and ideas to adapt to the way we work. Always probing, always listening and always thinking, Quentin teased out the data we needed, never afraid to ask the difficult questions.
