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.

Rooted in reputation, with over a century of expertise in comprehensive and collaborative construction services, Quasius delivers true solutions that stand the test of time. 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.

We move with purpose to honor our history of hustle, working every day to live up to the Quasius legacy in our constant quest to be the best for each other and our partners – emulating an essence of respect, feeling of family, passion for problem-solving, focus on fun, and belief in construction as an investment and legitimate testament to those who will engage with the environments created.

Quasius’ ideals and identity inspire us to support your goals through value-maximizing spaces that capture your mission and transcend your vision. Our holistic work encompasses construction management, financial planning, education, consensus building, volunteer coordination, fundraising, and marketing.

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.
