Ascot Group has appointed Marc Amen (pictured above) as chief executive officer for North America. His appointment will take effect upon the completion of his current professional obligations later this year.

In this role, Amen will oversee operations for Ascot’s US and Bermuda-based insurance and reinsurance businesses. He will also join the Ascot Group executive committee and report to group CEO and president Jonathan Zaffino.

Amen comes to Ascot from RenaissanceRe, where he spent more than 12 years, most recently as senior vice president overseeing underwriting and operations for the company’s US platform. His prior roles include vice president positions at Alterra Re and Harbor Point Re, and associate roles at Chubb Re and Lehman Brothers.

Amen holds an MBA in finance from Columbia Business School and a bachelor’s degree in history from Duke University. His earlier career includes roles in investment banking and reinsurance, contributing to a total of more than two decades of experience in the sector.

Zaffino said that he expects Amen, in partnership with Matt Kramer and Justin Keith, to help advance Ascot’s efforts in North America.

Ascot Group appointments

Earlier this year, the re/insurance group also revealed several key leadership appointments as part of its ongoing strategy to enhance underwriting performance and expand its US marine operations.

The appointments included Eric Herman, who has been named group head of underwriting performance management, a newly created role based in Iselin, New Jersey. Jon Mosby has also been appointed deputy chief underwriting officer, US marine and property, reporting to US chief underwriting officer Jesse Paulson.

Replacing Mosby as head of inland marine, Ascot US, is Dustin Jones, who will be reporting to Pat Stoik, head of US marine.

​In 2024, Ascot Group also reported gross written premiums of $3.8 billion, reflecting a substantial increase from previous years.
