In 1984, David and In Sun Moon founded Sam Moon Trading Co. as a wholesaler and retailer in Dallas. After their initial success in retail, Sam Moon Group started developing its own Class A shopping centers in cities where they wanted to expand.

In 2017, Sam Moon Group developed and opened their first Full Service Hotel called the Renaissance Dallas at Plano Legacy West. Their transition into hospitality was a huge success. With the knowledge and experience from the Renaissance, they developed the Hyatt Regency Frisco at Stonebriar Centre and the first JW Marriott in Dallas. With the successful opening of 3 major Full Service Hotels within 7 years, Sam Moon Group is widely recognized as one of the best Full Service Hotel Developers in Texas.

Building on their success in Commercial Real Estate, Sam Moon Group is currently developing a 70 acre mixed-use development in North Houston called Metropark. The first phase includes 325,000 sqft of restaurant, retail, & entertainment, a 148 key Hyatt House Hotel, and 307 units of luxury apartments.
