What Keller, Inc. does
Keller, Inc. is a 100% employee-owned design-build general contractor and construction management firm headquartered in Kaukauna, Wisconsin, in continuous operation since 1960. The company delivers commercial construction projects through an integrated team of in-house planners, architects, and builders, providing design-build services, construction management, and ground-up construction across 18 specialty sectors including healthcare, office, manufacturing/industrial, municipal, hospitality, agriculture, automotive/aviation, education, financial, religious, retail, restaurant, recreation, warehouse/self-storage, and senior living.
The company's underlying delivery model is design-build integration, in which architects and builders operate as a single team from project inception through completion. This is supplemented by construction management engagements, particularly for municipal clients. Keller's geographic footprint is anchored by four Wisconsin offices in Kaukauna (Fox Cities), Germantown (Milwaukee), Sun Prairie (Madison), and Wausau, with additional project activity in Minnesota and Illinois. The firm is recognized as Wisconsin's #1 and the nation's #4 Top Metal Builder and has won multiple Associated Builders and Contractors Project of Distinction Gold Awards and Excellence in Design Awards.
Keller generates revenue through project-based, quote-driven commercial construction engagements with no publicly disclosed pricing tiers. Go-to-market is direct enterprise field sales via referrals, repeat clients, and direct engagement with organizations across its target sectors. In February 2026, Keller acquired Hoffman Planning, Design & Construction, an Appleton-based design and construction management firm, which now operates as 'A Keller Company' while retaining its brand and operational independence, signaling a programmatic acquisition strategy.
