"Veteran instinct meets cutting-edge AI"

Trust built on experience — a professional you can rely on

Philosophy

Investigation is science,
and defense is art.

A graduate of Seoul National University, I served 21 years in the prosecution as Chief Prosecutor at the Seoul Central District Prosecutors' Office and Deputy Chief Prosecutor at the Gwangju District Prosecutors' Office. Having held key planning positions at the Ministry of Justice and the Supreme Prosecutors' Office, my exceptional organizational management and problem-solving abilities have been proven. Experience handling over 30,000 cases across all fields including criminal, corporate/economic, tax/finance, and election/labor is my asset.

I provide effective solutions with One-Step service covering both civil and criminal matters. I will be a reliable partner who heals clients' pain and brings new hope.
