Martenson & Eisele

Martenson & Eisele was founded in 1977 with a vision to become the premier civil engineering and land surveying firm in the Fox Cities region. Over four decades later, we have grown into a full-service firm offering planning, environmental assessment, engineering, land surveying, and architectural services across Wisconsin. Our employee-owned structure ensures a culture of accountability and client-centric focus, with two offices in Menasha and Omro serving communities like Appleton, Green Bay, and Oshkosh. We prioritize integrity, technical excellence, and community impact, delivering customized solutions for land development, public works, and community planning projects. Our team combines deep local knowledge with cutting-edge technology to address complex challenges in zoning, environmental compliance, and infrastructure design.

We maintain open communication throughout every project phase, ensuring clients remain informed and aligned with our deliverables. Our commitment to quality extends beyond technical precision to include exceptional service, as evidenced by our long-standing relationships with municipalities, developers, and private clients. We actively track regulatory changes and emerging technologies to provide forward-thinking solutions that position clients for success. While our methods evolve, our core values of trust, quality, and community stewardship remain unchanged since our founding.
