history ofmuller engineering company

We started as a small, civil engineering firm specializing in stormwater and floodplain management, owned by one passionate water resources engineer, Larry Muller. Larry incorporated Muller Engineering Company on March 17, 1980, added two team members, and started the company’s first project – a floodplain study on First Creek in Aurora, Colorado. Muller’s first construction project, Sanderson Gulch at Allison Street in Lakewood, followed in 1981. Muller added a transportation planning and design group and a water and wastewater utilities group in 1984. We designed our first significant transportation project as a prime consultant in 1987 on US 287 in Broomfield, the same year we reached $1 Million in revenue. In the years that followed, we touched every corner of our state and expanded our services to include traffic engineering and intelligent transportation systems, structural and bridge design, program management, and environmental services.

Larry was a very involved father, engineer, and businessman. He served as president of the American Society of Civil Engineers Colorado Chapter, president of the American Council of Engineering Companies of Colorado, chairman of the Board of the West Metro Chamber of Commerce, and chairman of the Board of Red Rocks Community College. He received several honors during his career and posthumously. In 1995, Larry unexpectedly passed away. Nine Muller employees established the Employee Shareholder Legacy model that Muller continues to operate under today.

Muller steadily grew from one to 17 employees in the first 10 years. By year 20, we reached 30 employees, 49 by year 30, and upward of 130 employees by our 40th anniversary. Always headquartered in Lakewood, Muller continued that tradition with our move into Belmar in 2022.

Meet the Shareholders

As a company owned by 20 key employees, Muller’s corporate structure provides our clients with the stability of legacy ownership. Every project has the leadership and commitment of a corporate shareholder at the Project Principal level, and most also at the Project Manager level.
