Building relationships since 1891


Construction of any kind is a quest to build your best, a physical and financial commitment to elevating the environment around you. Breaking ground on a project is a palpable, even brave proclamation to bring forth change or begin a brand new chapter. To craft an upstanding structure or optimize an existing system, you need an empowering construction partner with integrity and experience from concept to completion. An advocate – from the ground up.

We embrace the joy of the journey and dig deeper as dedicated teammates, guiding projects with strategy and a safe sense of urgency to turn your design dreams tangible.

It's ALL History

1891 - Our Beginning

With a horse named Daisy and a foot-powered saw, George Quasius founded his own residential construction company as a carpenter-contractor, constructing many of Sheboygan’s finer homes.


George’s sons Arthur, Raymond, and Leslie join the business, changing the name to Quasius & Sons and expanding to light commercial and industrial construction.


Quasius becomes a major regional commercial, residential, and industrial construction company, changing to incorporated, called Quasius Bros., Inc.


Quasius Bros., Inc. collaborates with Kohler Co. and the Village of Kohler to construct Kohler Memorial High School & Theatre. The company also contracts several projects for Sheboygan manufacturing, warehousing, and office facilities, including the restoration of the Wade House.


As the construction market changes, so does Quasius. The company broadens its scope to construct forty department and discount stores for H.C. Prange Company across three Midwestern states. The company also reconstructed Kohler’s American Club as a luxury hotel complex.


Under President Dave Quasius, Quasius Construction adds Construction Management as a natural extension to its list of services, providing more informative, collaborative, and cost-saving options for clients. Quasius Construction also embraces new technology by launching its first company website!


Quasius grows to include outstanding pre-construction and design-build services, guiding clients through all construction phases with Matt Quasius as Director of Operations and the company continuously striving to improve and innovate.


Quasius continues to foster a century's worth of construction capabilities in crafting ideal environments through a transparent, dynamic process administered by a talented team experienced in going the extra mile. Special Projects are also emphasized, with the division dedicated to taking complex renovations or remodels and delivering cost-effective, solution-centered spaces at any scale.

Evolving for the future, Quasius honors a history of hustle by innovating systems and strengthening our foundation for a second century of excellence.
