Brian Byrne, an engineering graduate from Marquette University, and John Maliszewski founded Briohn Building Corporation in 1979. The company name came from the union of Brian's and John’s first names. Their first project together was remodeling/restoring a fire damaged building owned by Mitchell Manufacturing.  The company is now in its second generation of family ownership, led by CEO Nelson Williams and Brian’s daughters Katy Williams and Breann Mila. 

Since that first project, Briohn’s unwavering focus on customer service and quality construction practices has resulted in thousands of successful projects and happy customers. In fact, on a yearly basis, more than 60% of our projects come from repeat customers.

In the course of over a 40 year history, we have had the pleasure of working with multiple generations of owners at several companies, continuing to provide the construction excellence that has helped their businesses to grow.

Offering opportunities for personal and professional growth, Briohn attracts and retains the best. Many on our team have been with us for two or more decades.  In 2014, we celebrated two employees with over 30 years of service, three with over 20 years, and 15 employees with over 10 years of service.
