The 2027 Executives to Watch: East Re Insurance’s Kevin Sullivan

Kevin Sullivan, Head of Property Reinsurance | East Re Insurance, LLC, an AmTrust Company

In October, Kevin Sullivan helped launch and now leads AmTrust’s newest company, East Reinsurance Services (East Re), a treaty property reinsurance business focused on providing proportional treaty solutions for insurers across North America.

The new platform combines underwriting, actuarial, catastrophe modeling, and claims expertise. Since assuming the role as Head of Treaty Property, Kevin has focused on positioning East Re for profitable growth and innovation in and out of market cycles.

“Our primary goal is to build a consistently profitable and sustainable specialty treaty reinsurance underwriting and portfolio management platform focused on U.S. property and specialty business, that is recognized for underwriting expertise, disciplined risk selection, and long-term partnerships,” Sullivan said, in response to questions from Risk & Insurance.

“As market conditions evolve, we are focused on growing the business thoughtfully, not simply increasing premium volume.

“Success will be measured by the quality of the portfolio, the strength of our broker and client relationships, and our ability to deliver stable capacity in and out of various market cycles,” he added.

Prior to joining AmTrust in 2024 to build the company’s E&S Property division, Kevin served as Head of Specialty Property at AXA XL Reinsurance, where he was responsible for portfolio management, underwriting strategy, pricing, and business development. Sullivan is optimistic about the prospects for the new venture, drawing, as he is, from the experience of almost 30 years in the insurance business.

“One of the most important lessons I’ve learned is that sustainable success is built on expertise, discipline, and relationships,” Sullivan said.

While market conditions inevitably change, clients and brokers consistently value partners who are knowledgeable, responsive, and committed to supporting them through various market cycles. Establishing a culture centered around underwriting excellence and long-term thinking has reinforced the importance of being focused on portfolio quality rather than chasing premium.

“What has gone well is our reputation in the marketplace. We’ve been able to leverage our past relationships with brokers and clients and build a diversified portfolio supported by disciplined underwriting,” Sullivan said.

The new group’s portfolio will initially focus on pro rata treaty accounts across E&S property, high-value homeowners, specialty property, inland marine, and builders’ risk, As any insurance leader will tell you, it’s no small task to maintain underwriting discipline in the face of competitive markets.

“The greatest challenges are likely to be the same challenges facing the broader reinsurance industry: maintaining underwriting discipline as competitive pressures increase and navigating a more complex catastrophe and climate risk environment,” Sullivan said. “Ultimately, our goal is to continue building a business that combines technical expertise, strong relationships, and consistent execution. If we remain focused on those fundamentals, we will be well positioned to create lasting value for our clients, brokers, and organization.”

Sullivan is a graduate of the York College of Pennsylvania and put in previous stints at Montpelier Re, AXA XL and Catlin, among other entities. &
