About me

NY/International Attorney Sean Hayes grew up in Connecticut and New York to an Irish-immigrant father and an Italian mother. He is a U.S. and Irish National that is a permanent resident of Korea. He received his legal education in Korea, the U.S. and the U.K.

Sean Hayes is the first and only non-Korean to be employed as an attorney by the Korean Court System (Constitutional Court of Korea) and one of the first non-Koreans to be a full-time regular member of a Korean law faculty.

Korea Law Firm

He is known over his 14+ years in Korea for his aggressive advocacy and candid NY-style street-smart advice. Sean is, also, one of the few attorneys in Asia that has experience managing non-consulting companies and working as an interim HR Manager. He worked as an interim General Manager/Director for Oil & Gas, New Tech, Pharmaceutical, Franchise and Manufacturing companies.

He regularly appears in and is quoted by international media organizations including the NY Times, Wall Street Journal and international law journals. In his free time he enjoys playing golf, sailing, drinking beer and carousing with his rowdy friends.
