History of the Business
The Dotzauer family window business started in 1986 with three brothers Joe, Jeff and Dave. Their business spanned throughout Milwaukee and surrounding areas of Wisconsin, as they served in manufacturing windows, built historic replication windows , provided the installation of windows, and truly encompassed all things commercial and residential with windows. Steadily growing the business, Dotz Brothers became known as a quality name you can trust.
In 1986, Joe Dotzauer's growing family was blessed with the arrival of twin boys, Jesse and Dustin Dotzauer ! . . . read more here https://www.dotzauerbrothers.com/about
