Mosaic Insurance has opened an office in Frankfurt, Germany as part of its global growth plan. The new location will facilitate the high demand for cyber and transactional liability coverage through Europe. Joining the German office as director of Mosaic’s European entity and head of Europe will be cyber risk specialist Dennis Bertram (pictured middle). M&A specialist Eileen Siemer (pictured right) will also be appointed to the Frankfurt office as a member of Mosaic international transactional liability team. Bertram previously worked as a cyber and crime product manager at insurtech Finlex. Before that he was a lead cyber underwriter for Germany, Austria, and Central and Eastern Europe at insurance company AXA X. Siemer will underwrite M&A risks to develop Mosaic’s transactional liability business in the Germany, Austria, Switzerland (DACH) region. She joins the firm from RiskPoint, where she underwrote warranty and indemnity insurance in its M&A group. Cyber specialist Aron Zeiler (pictured left) has also been appointed to Mosaic’s Frankfurt office and will support the cyber division’s European build-out. He began his career at Swiss Re in Germany, becoming a lead underwriter for Swiss Re in Zurich. David White, Mosaic’s underwriting director, says: “We’re delighted to welcome Dennis, Eileen, and Aron to build out our reach in Europe, where Mosaic can offer the advantages of Lloyd’s A-plus ratings and much-needed capacity across complex lines of business thanks to both our syndicate and our trade partners.” Bertram adds: “We’re thrilled to be able to offer our capabilities and capacity to clients in Continental Europe’s largest insurance market. Frankfurt represents a vital hub, from which we can serve high client demand, as well as access business opportunities in other markets.”
