About Stahly

At Stahly Engineering & Associates, we are an employee-owned, full-service civil engineering and surveying firm dedicated to building positive relationships through the delivery of high-quality services. Our success stems from the personal involvement of our employee-owners in every project and community we serve, reinforcing our commitment to our clients’ goals.

We offer comprehensive engineering services in transportation, site development, municipal, and structural engineering. Additionally, we assist public and private clients with planning, grant writing and administration, GIS, various surveying services, and construction inspection.

The inspiration behind Stahly Engineering’s business philosophy is the founder, J. David Stahly (Dave). “It was Dave’s ethics and family values that drew me to Stahly Engineering in the first place,” states Greg Benjamin, President/CEO. “We intend to carry on the legacy of what he started.”

Moving his family to Helena from Arizona in the late 1960’s, Dave was working on a project for an Arizona based firm. He and his young family liked Helena so much they decided to stay. Staying in the area meant starting an independent firm. Stahly Engineering’s foundation was made solid with the help of the entire Stahly family. Dave’s wife Carol along with Mark, Mike, Byron, Alana and Dan all participated in various jobs as the company grew.

“Dad’s influence on us was always by example,” Byron Stahly said. “What Stahly Engineering is today is a direct result of Dad’s life principals of hard work and integrity. I know how valuable an influence in my personal and professional life my father has been.”

Stahly Engineering recently became an all-employee owned company. Principals of the firm manage the day to day operation of the firm:
