Keller celebrates 60 years

Founded as Keller Structures in 1960, the Keller name has grown the last 60 years into who we are today: Keller, Inc. – Planners | Architects |
Builders, an award-winning single source, design/build firm headquartered in Kaukauna, with offices in Madison, Milwaukee, Tomah and Wausau.

Consistent growth
Keller, Inc. has consistently shown progress in all areas of the organization. Starting with one building erection crew and growing to 45 full-time crews, beginning as an agricultural builder to having decades of expertise in the commercial and professional industries, and by expanding our original footprint in Kaukauna well beyond Wisconsin. With our in-house team of Architects, Interior Designers, Project Managers and Field Crews specializing in Concrete, Building Erection, Rough Carpentry and Finished Carpentry, we are able to provide innovative design/build services to commercial and agricultural industries throughout the state of Wisconsin and the Midwest.

Evolution of our ESOP
One of our founders, Walter Keller, oversaw the company’s transformation from a family-owned business to an employee-owned corporation through the Employee Stock Ownership Plan in 1986. Keller, Inc. gradually transitioned ownership and by 2005, officially became 100 percent employee-owned. Walter retired as president in 1989, but his original values of integrity, honesty and commitment to putting the customer first still inspire today’s highly dedicated professional and field staff. Led today by CEO Wayne Stellmacher and President Cory Vande Wettering, we currently have more than 265 employee owners who take pride in designing and building every project as if it were their own.

Mission statement:
To provide design/build construction services to
all of our clients in the following manner:
1.) To conduct our business with unyielding integrity and honesty.
2.) To complete every project as if we were building for ourselves.
3.) To treat all Clients, Co-Owners, Subcontractors and Vendors the way we would want to be treated.
