Who we are

In 1986 our Managing Partner, Mark O’Brien, started work in the travel industry on a government sponsored youth training scheme with work placement at the Irish national airline, Aer Lingus and the Greek national carrier, Olympic Airlines. Mark’s journey in the corporate travel industry began, which has transcended through memorable companies that have ranged from setting up the first corporate travel agency in Pinewood studios servicing the travel needs of some of Hollywood’s biggest blockbuster movies, to becoming the youngest global managing director of a Top 4 travel management company and leading several companies through mergers and acquisitions. Mark’s passion has always been consulting and he set-up one of the first global consultancy firms dedicated to corporate travel, meetings, payment, and expense. From here he gained invaluable experience and insight into some of the world’s largest companies. To complete this stage of his journey, Mark latterly led global business development for a Top 3 travel management company, which completed his 360-degree view of the industry.
