Song I Yoon and Hee Bong Park began their careers together at Deloitte Tax Korea in 2007 — both working in international tax services for global corporations and expatriates. Over the following years, each built deeper expertise in Korean domestic industries, gaining an inside view of how Korean businesses actually operate.
In 2016, they joined THECL Accounting Corporation together, where they ran a boutique practice serving foreign-invested companies for nearly a decade. During that time, they assisted over 100 foreign companies — from the US, Europe, and Asia — in establishing and operating in Korea, managing ongoing tax, payroll, and compliance across industries including manufacturing, consulting, and IT.
In 2024, the team took the next step: building their own independent practice and forming a strategic partnership with STAR LAW — a Korean law firm — to offer clients a more comprehensive, seamlessly coordinated service across tax, payroll, and legal compliance.
