My focus will be on disciplined and sustainable growth, built on underwriting excellence, clear communication, and strong partnerships with our brokers and clients. HDI has strong momentum in Japan, and I look forward to contributing to the next chapter of development together with the team.”
Casey Sandler, who has successfully managed the Japanese branch on an interim basis since August 1st, 2025, has decided to continue his career outside of the company.
“We would like to thank Casey for his commitment and the valuable contributions he made in the various roles he held at HDI Global Japan. His leadership strengthened our position in this dynamic market. We are sorry to see him leave and wish him all the best for his future endeavours,” concluded Hullin.
