Owners Pat and Adam

In our industry, it is an honor to have a reputation
as a high-quality service provider.

Founded in 1989, MahlerClean has steadily grown throughout the years and today is owned and operated by Patrick Sullivan and Adam Brauhn, two long-term senior executives. The two now serve as President and Vice President and lead more than 850 skilled service representatives in maintaining 12 million square feet of office, industrial and educational, medical and institutional space each day.

As the business has grown, the company has expanded service to include clients located in Madison, Racine/Kenosha, and Sheboygan. We have satellite offices in each of these regions to serve as hubs for employment interviews and training, inventory and equipment, and offices for our local management team.

The MahlerClean team has the experience and expertise to deliver a consistent level of service so that our clients may focus on their core businesses. Our recipe for success is not a complex one. We believe in compensating our service representatives with a competitive wage in return for providing our clients with well-maintained facilities. When our high standards align with our clients' expectations, we are confident in our abilities to provide your clean start each day.

We believe happy employees lead to happy clients, and we’re thrilled to be recognized as a Top Work Place for many years running!
