About Us

Our History

Maertens-Brenny Construction Company was founded in 1980 by Joseph D. Maertens and Severin Brenny out of their homes. The company soon moved into its own offices as projects began to schedule out. In 2006, John Hoffman and Scott Chapman became co-owners with Joe Maertens. John and Scott then acquired total ownership in 2016. Both Scott and John began their careers with Maertens-Brenny and are excited to innovate as the industry changes.

As a small business, we are a  general contractor and construction management firm with big self-performing capabilities!


President & Co-Owner

John began his career in 1995 and has been with Maertens-Brenny for his entire career. He holds a Bachelor of Civil Engineering from the University of Minnesota. John’s key responsibilities include company operations, oversight of project teams, corporate strategy, and client relationship development. John is an open book and prides himself on transparency with our clients, which is evident in our bidding process and project delivery.

John is all about the outdoors, no matter the season. He enjoys being outside, whether it is activity-based like hunting or fishing or just spending time on the lake in the summer with his wife and kids. He is really looking forward to enjoying more adventures with his wife while traveling the world.

"Scott" Chapman

Vice President & Co-Owner

Scott, as he’s known around the office and job sites, has been with Maertens-Brenny since 1989. He came to the company from the Navy Construction Battalion “Seabee.” His construction experience ranges from utility projects, office buildings, sports facilities, and retail projects. As Vice President, Scott oversees field operations, safety management, and labor negotiations. He’s an active member of the North Dakota Safety Council, and AGC of Minnesota.

In his spare time, Scott enjoys fishing, boating, and spending time with his five kids and wife. During the summer, Scott’s family soaks up all the remarkable aspects of life in Minnesota – mostly centered around lake life. Construction projects don’t stop at the end of the day as Scott always has a project underway on the home front.
