About us GSG


In 1992, Guillermo Garcia and Arturo Saenz created GSG as an environmental services company. Since then, GSG Consultants, Inc. has developed into a dynamic and diverse engineering and consulting firm, performing an array of environmental construction services. Today, GSG is a leading minority-owned and disadvantaged business enterprise (MBE/DBE) providing services in the transportation, building and facilities, and land development markets. GSG was established with the mission to deliver value-added consulting services by embracing the core principles of integrity, quality and reliability. These principles served initially to set the direction for the company and continue today to drive our growth and delivery of services.
