Founded as a geotechnical specialty firm in 1970, Langan quickly became involved in many large, complex projects located throughout the eastern part of the United States. As their growth continued, they leveraged their highly technical base to expand into the civil engineering and environmental disciplines.

Their client-focused, highly entrepreneurial culture helped evolve additional technical capabilities and enable geographic expansion into the southeast and western regions of the United States. Langan International was formed to support global clients and partner with the world's elite design and construction teams around the world.

After five successful decades, their reputation for providing innovative solutions that yield measurable value for their clients continually forges new enduring relationships for the firm and distinguishes Langan from the competition.
