Profile
Byoung-Ho Son, Attorney, graduated from the Korean National Police University (Class 19) and served as a police officer (Police Lieutenant) for eight years beginning in 2003. For six of those years, he was engaged in investigative practice with the Intelligent Crime Investigation Unit, Cyber Crime Investigation Unit, and Economic Crime Investigation Unit of the Seoul Dongjak Police Station, as well as the Voice Phishing Task Force of the Korean National Police Agency.

Based on this practical experience, Attorney Byoung-Ho Son began his legal career with the Criminal Practice Group of Kim & Chang in 2012, handling criminal matters involving corporate crime, medical/healthcare, trade secrets, intellectual property, finance, antitrust, tax, broadcasting and telecommunications, personal information, and China-related issues. In 2015, he joined Hyun Law, where he led the Criminal Practice Group for ten years, and since 2025 has been practicing as a criminal law specialist at One Law Partners, LLC.

In addition, Attorney Byoung-Ho Son has provided professional and strategic advice on criminal risks and related disputes to clients from various fields, including business leaders, journalists, prominent entertainers, and athletes, and is widely recognized as a distinguished advocate who carefully safeguards the social standing and reputations of his clients.
