From humble beginnings to Houston's most trusted general contractor. We design, build, and manage projects that shape communities across America.
What began as a small janitorial service with part-time employees has grown into a powerhouse general contracting firm serving the nation.
Jason Yoo founded HBS National Corporation in Houston, starting with janitorial services for plants, refineries, and industrial sites along the Houston Ship Channel. Clients grew to include DuPont, Valero, Marathon, and Shell Motiva.
Expanded into general contracting, building the 100,000 sq ft Harwin Center and Delta Plaza shopping centers. Now serving industrial, commercial, government, retail, and restaurant sectors.
Acquired a concessions contract at Bush Intercontinental Airport Terminal C, launching JDDA Concession Management — now operating at 6 major airports nationwide with $25M+ in annual sales.
