A tradition of excellence and innovation.

Foth has a long, rich history dating back to 1938. Since then, our services, locations, and membership have expanded to meet the changing needs of our clients. Check out some notable milestones from our past.

1938
A young electrical engineer, Herbert S. Foth, organized a small engineering company in Green Bay, Wisconsin. That first year, Foth had four members on the payroll, and our clients included several municipalities in northeast Wisconsin.

1939 – Early 1940s
Foth and Patrick Boyd joined forces as Foth and Boyd. The company also began a long-term engineering relationship with Austin Straubel Field, now Austin Straubel International Airport.

Mid-1940s
We employed approximately 24 members. Patrick Boyd left the partnership and the business continued as Foth & Porath, Inc. Many municipal clients who were added during this time continue to work with Foth to this day.

1950
Jack Horner, World War I pilot and former Federal Aviation Administration official, joined our company to form Foth, Porath & Horner. The firm specialized in airport engineering and served clients throughout the upper Midwest.
