John Aum has over 40 years of experience in the field of construction , where he has completed numerous large scale residential, commercial, hospitality, and other specialty projects.

He currently serves as President of Samwon Construction. Mr. Aum found his passion and drive for construction when he was first entrusted to build his parents’ house in 1973 while he was still in college. This passion led him to start his first company which focused on metal framing work.

From there on, he continued to build upon his work and experience. Prior to the establishment of Samwon Construction, Mr. Aum supervised the construction of a department store, several major high-rise buildings, and completed well over 2,000 apartment units, as well as construction of multiple golf courses. As he continued to work on large scale projects, one of his achievements was connecting major gas lines between cities with governmental subcontracts, including the Incheon International Airport, the largest and busiest airport of South Korea. As a believer in developing innovative projects and pushing new boundaries, he also enabled the mass adoption of gas water-heaters in South Korea by directly working to deregulate the import of foreign-made gas water-heaters.
