Our Company History

McMahon began as a small civil engineering firm in 1909, providing services to those in the Wisconsin Fox River valley. After more than a century in business, we remain rooted in the core values that founded us – providing unmatched service for our clients and building long-standing relationships. We attribute these values to our success and growth over the last 100+ years. Our firm now has offices in Illinois and Indiana in addition to our corporate headquarters in Neenah, Wisconsin. We have designed and managed projects across the country and even internationally. Our offerings have expanded, and we’ve established affiliate companies. And still, we maintain a personal, small-business touch while delivering our professional services throughout Appleton, the Fox Cities and far beyond. 

As engineers, architects, surveyors, technicians and more, our team at McMahon shares one common goal – to understand our clients’ objectives, connect with their vision and make it happen. Through every service we provide, our focus is not only on producing an end-result that is of quality but to earn trust and build long-term relationships of our clients.

When you choose McMahon for a project, you’re gaining a member of your team. We share in your excitement and problem-solve any challenges right along with you. We respect what you do and any constraints you may be under. Our experience allows us to see the promise behind your ideas, and we have the diverse expertise to transform those ideas into reality.
