Miller has made four senior appointments to establish a new marine team as part of its continued expansion in South Korea.
KyungSeop Shim will lead the new unit as head of specialty. Shim previously held senior positions at Marsh Korea, including head of specialty and head of marine. He also ran a shipping company for five years. In his role at Miller, Shim will focus on building out the firm’s marine offerings in the Korean market.
Three other senior professionals also join Miller from Marsh Korea. Justin Roh brings more than 15 years of experience in protection and indemnity (P&I) claims and legal affairs at Hyundai Merchant Marine, as well as five years of broking experience. At Marsh, he worked across property and marine lines, including P&I, hull and machinery, terminal, transport, and logistics risks.
Hana Jung, previously vice president at Marsh Korea, handled a portfolio of direct P&I and FD&D business, and managed retail and reinsurance programs for hull and machinery, war risks, and kidnap and ransom (K&R) coverage. Her background also includes legal and insurance roles in the shipping and logistics sectors, along with international experience through training and work in London.
Jayce Park also joins the new team, bringing experience in retail broking and facultative reinsurance placement across P&I, hull and machinery, and container risks. Prior to that, she managed insurance and reinsurance claims for marine, aviation, and liability lines.
The formation of the marine team follows Miller’s opening of its Korea office in January, led by David Kim (pictured above). The launch marked the broker’s formal entry into the Korean market and was positioned as part of a broader strategy to develop a dedicated regional hub in Seoul.
“Bringing KS and the team on board allows us to focus on growing our marine proposition in the region and further establish Korea as a meaningful location for Miller. Over time, we expect to expand into other lines as we capitalize on the potential for close collaboration with our strong foundations in the London marine market,” Kim said.
The move also comes during a period of growth for the firm. In 2024, Miller reported £271 million in revenue, up 13% from the previous year, along with an EBITDA margin above 30%. Gross written premium surpassed US$4 billion, driven by 12% organic growth across its specialty divisions.
The firm’s workforce grew significantly during the same period, with more than 200 employees added in 2024. The expansion brought total headcount to over 1,100, with resources allocated to several emerging markets and niche business units, including marine and specialty reinsurance.
