Coulson Partners

In the company's own words, 'Coulson Partners delivers strategic advice tailored to solve business critical problems, seize opportunities and drive smart, long-term decision making.'

The firm states: 'We have become trusted advisers to CEOs, founders and leaders who depend on our experience, clear thinking and straight-talking on corporate strategy, reputation management and communications.

'Our clients lead both public and private businesses, private offices and influential organisations spanning diverse sectors.'
