With more than 50 years of experience in insurance and reinsurance brokerage, Mark Shilton, an Associate of the Chartered Insurance Institute, offers his clients first-rate expertise both internationally and in the French market. Early in his career, he headed the International and Reinsurance Division at CECAR, which later became Marsh France.
As a key account manager in Europe, the U.S., and Asia for over 15 years, Mark also headed operations at the Groupement de Réassurance Français, which was later acquired by Guy Carpenter France, before founding his own company, MSI, in 1996.
Anticipating the needs of the direct insurance and reinsurance markets, which were undergoing major restructuring, Mark focused his efforts on developing “specialty broking,” investment, and “excess and surplus lines,” and today concentrates on underwriting as a Managing General Agent (MGA).
Keeping pace with and anticipating market trends, MSI has diversified its product line and is now a major player in affinity insurance, construction, miscellaneous financial losses, and specialty risks.
