Every project we take on reflects the Altmann legacy: a commitment to doing the right thing, treating clients like partners, and standing behind the work long after the job is done. It’s how we’ve earned the trust of commercial clients, municipalities, and community partners across Wisconsin — and how we plan to keep earning it for generations to come.

With design-build, there’s no hand-off between separate firms.
