Building The Future Together



Hunzinger Construction Company is a fourth generation, family and employee-owned company that continues to serve the construction industry in Southeast Wisconsin since 1907. We boast a lengthy roster of employees whose families have worked for Hunzinger for two and even three generations. For decades, we have fostered a family environment. Employees and owners mingle on the job and off – on beams and in tunnels, at barbecues and ball games. We are truly “a family company.” Our workforce reflects our strong company culture of pride, diligence and commitment to customer service. 

People love working here and we do everything we can to make sure our clients love working with us, too.
