Marsh Re has appointed Oliver Marko (pictured above) as chief broking officer for its facultative reinsurance team in Germany and Austria, adding a broker with more than 20 years of experience across the insurance and reinsurance industry to its growing European operation.
Marko joins from Aon, where he spent more than seven years in facultative broking roles based in Cologne, Germany. He most recently served as head of sales for facultative business across the D-A-CH region and held the title of divisional director, a position he took on in July 2023.
Prior to that role, he led Aon's facultative sales operations in Germany for nearly three years and managed facultative reinsurance client relationships in an earlier position at the firm. He joined Aon in March 2019.
Before moving into broking, Marko held underwriting and retrocession positions at several carriers. He spent more than a year as senior retrocession manager at SCOR in Cologne, before which he worked for over four years as an international property facultative underwriter at Aspen Re. He also held an underwriting role at Hiscox in 2012.
Marko began his reinsurance career at Willis Re in London, where he worked as a property treaty broker from 2009 to 2011. He had earlier completed a part-time placement in life reinsurance at Deutsche Ruckversicherung AG while studying, and started in the industry as an insurance clerk at Allianz in Stuttgart, where he completed a three-year apprenticeship.
He holds a Bachelor of Arts in insurance and actuarial science from Cologne University of Applied Sciences.
Marsh Re said the appointment would "significantly strengthen our regional capabilities and support our continued growth."
The firm noted Marko's background in facultative broking, underwriting and retrocession as factors in the hire.
The appointment is part of a wider European facultative buildout at Marsh Re. The firm named Francesco Liverani as head of business development for facultative reinsurance in Italy in February 2026, as compulsory natural catastrophe insurance requirements in Italy and Greece reshape demand across the region.
