Building a Shared Vision

In the late 1980s, two young construction professionals—Jeff Donovan and Jeff Kowalik—met while working together on a variety of commercial construction projects. They shared a vision of building a general contracting company that would encompass time honored construction practices and new innovative ideas while providing outstanding customer focus and service.

They created Northcentral Construction in 1990, laying the foundation of what is now a thriving, growing construction firm. Through their hard work, dedication and focus they built a solid, financially stable company that provides a better construction experience to the developers, subcontractors and employee team members throughout Wisconsin. They continue to stay active in the company as co-chairmen of the board.
