From our first project in San Antonio in 1909 as W.E. Simpson Company, through the expanded capabilities of Simpson Group, and now as HDR, our name has been synonymous with reliability and innovation in San Antonio for almost 100 years.

HDR is a full-service firm, with the ability to provide a broad range of expertise in transportation, water/wastewater, water resources, facility design, structural design and forensics. Stability and growth through both good and bad economic times is the direct result of our approach to our work. We believe that quality design leads to the safest, most useful and cost-effective solutions. Construction and functional details receive full consideration in project execution. Strong and well-qualified managers are placed in charge of all projects. This client-based philosophy is reflected in the fact that HDR San Antonio has industrial, governmental and private-sector customers that have been our clients for over 50 years.
