Brian Burwell has recently transitioned to a senior advisor role at Marakon. In concert with this change in role, I, along with the global partner team, want to take this opportunity to recognize and celebrate Brian’s truly exceptional and impactful career at Marakon.

There are few people who devote 37 years of their career to one company. Brian joined Marakon as a Stanford MBA in August 1979, just one year after the firm was founded.  Over the course of his career, he served as both CEO and COO of the firm, and has worked out of offices in San Francisco, London, New York, and Melbourne.

Brian’s work has spanned sectors including healthcare, consumer products, retail, hospitality, entertainment, and education. He has been critical to the success of many of Marakon’s biggest and most important flagship clients over three decades including: Diageo, Roche, Cadburys, Boots, IHG, Heineken and Prudential.  Brian can truly say he spent his career advising the CEOs of some of the world’s most admired companies.

On the firm front, Brian has always been passionate about our people and people development. ~10 years ago, Brian set an ambition to have a partner team with more gender diversity, and set the groundwork for a talent model that would support that ambition.  Perhaps one of his greatest legacies is the partner team he is leaving behind; one that is comprised of 35% women. 

As he embarks on his next chapter, Brian is continuing to pursue his passion for philanthropic consulting as a partner at Bridgespan, and as a member of the Dean’s Advisory Council at UC Davis. He will remain a senior advisor to Marakon, supporting us where his experience, expertise and relationships can be helpful.

Brian is also very much looking forward to spending more time with his grandchildren, traveling with his wife Bieke, and drinking more Brunello (which as he describes, can be paired with anything or can stand on its own).

Please join me in giving our deepest appreciation and thanks to Brian for all he has done for Marakon over the past 37 years.
