A LONG FAMILY HISTORY

Our History – an Experienced General Contracting Firm

Maas Brothers Construction, Inc., is one of Wisconsin’s oldest and most well-respected general contracting firms. Founded in 1922 by brothers Albert W. and Alvin (Ollie) Maas in Watertown, the growing construction business survived the Great Depression, with projects including Carillon Tower at UW-Madison, one of the most distinctive visual features of the campus (1936), and the iconic P.J. Jacobs High School building in Stevens Point, featuring murals, tiled mosaics, stained glass and an oak library (1938).

Maas Brothers thrived during the post-World War II construction boom. In the 1940s, Albert’s sons, Earl and Albert Jr., joined the family business. Together, they ran the company from 1949 until their retirement in 1990. During this time, Maas Brothers was involved with construction of Watertown Memorial Hospital, Marquardt Memorial Manor, Jefferson County Courthouse, Riverside Junior High in Watertown, and many more.

In 1990, Earl’s son, Robert Maas, took over management of the company. Operations expanded throughout the 1990s under Robert’s direction, with considerable contributions from Daniel Shea and Douglas Beilke, who are 2nd-generation members of the Maas Brothers team, and Kevin Kohlhoff. Clasen Quality Chocolate, Jones Dairy Farm, Watertown Regional Medical Center, Jefferson High School and Johnson Creek Schools are among our most notable modern-era projects.

Today, as we approach the company’s 100th anniversary, Maas Brothers continues to grow and evolve in an ever-changing construction industry. Together our team brings decades of construction experience to the business. Thanks to our longstanding reputation for providing quality construction work, many long-term clients—including some dating back to the 1940s and 1950s—continue to choose Maas Brothers Construction.

In addition to construction management, Maas Brothers self-performs a variety of trade work, including rough and finish carpentry, concrete and selective demolition. Supplying our own trade professionals helps us control quality and timelines to deliver projects on schedule and within budget.

Over the years, Maas Brothers has developed a strong network of construction industry relationships, including architects, engineers, vendors and subcontractors. These connections lead to better value engineering, lower subcontractor and vendor pricing, and maximum efficiency on projects of all types and sizes.

Today, Maas Brothers continues to grow and evolve in an ever-changing construction industry. The current management team of Doug Beilke, Kevin Kohlhoff, Anthony Maas, Tony Meyers, Daniel Shea, Mark Stafford, Eric Graf, and Trevor Kearns bring more than 200 years of combined construction experience to the table of this fourth generation business.
