MSIG USA has appointed Andrew Pateyuk (pictured) as head of retail and wholesale property, completing a property leadership structure the company has assembled at pace since August. Pateyuk joins from SCOR Business Solutions, where he spent more than seven years as senior vice president and head of property and power underwriting for North America, with responsibility for underwriting strategy, portfolio performance, and natural catastrophe capacity across the region.
The appointment follows two other senior hires in quick succession: Carrie Brodzinski joined as chief underwriting officer on August 18, moving from The Hartford where she led global specialty underwriting, and Oscar Aguilar was named head of excess and surplus property on September 29, arriving from Liberty Mutual. The three appointments together give MSIG USA a layered property structure, an enterprise underwriting lead, a dedicated E&S property head, and now a head covering the admitted retail and wholesale channels.
A technical hire for a complex book
Before joining SCOR, Pateyuk spent more than three years at Allianz Commercial in engineering underwriting roles focused on power generation and construction risks, and two and a half years at Munich Re Specialty as vice president of engineering underwriting, specialising in power plants, co-generation facilities, and hydroelectric and wind assets. His earliest years in the industry were at FM Global, where he held both underwriting and field risk engineering positions across Canada and the United States.
That combination of underwriting and risk engineering experience is relevant to the retail and wholesale book MSIG USA is building. The company has described its property appetite as covering “hard-to-place and hard occupancies” alongside standard commercial risks, and large industrial and power generation accounts are precisely where technical underwriting capability separates carriers in broker placement conversations.
CEO Peter McKenna said Pateyuk’s “understanding of the retail and wholesale markets will be instrumental as we continue to expand our capabilities while maintaining the discipline and consistency that underpin our long-term strategy.”
Building in a softening market
MSIG USA is expanding its property leadership at a moment when US commercial property rates have fallen for nine consecutive quarters, according to Marsh, with property down 10% in Q3 2026 following a 13% decline in Q2. Abundant capacity and intensifying competition have pushed rates lower across most account sizes, reshaping placement dynamics for retail and wholesale brokers handling commercial property risks.
In that environment, a carrier actively building dual-channel property capacity – with separate leadership for E&S and retail and wholesale, and an experienced engineering underwriter at the helm of the latter – is a placement signal worth tracking. The company launched MSIG Specialty Insurance America, Inc. as its E&S platform in May 2026, and S&P Global Ratings assigned the entity an A+ financial strength rating with a stable outlook at launch. Its admitted insurers carry A+ financial strength ratings from AM Best, affirmed in June 2026.
Pateyuk holds a bachelor’s degree in chemical engineering from McGill University, a foundation that informs his engineering underwriting background, and an MBA from Chadron State College. He reports to McKenna and joins a property leadership team that MSIG USA has rebuilt substantially over the past year.
