We Are Construction Professionals
Building since 1891, O‑A‑K offers commercial construction services to clients throughout the country, specifically West Michigan and Southwest Florida. We specialize in community-driven construction projects, offering a customized experience. Contact us and let's talk about how O‑A‑K can serve as your commercial contractor and construction partner.
We Make Construction Easy
We are engaged with the project from the earliest stages of planning, offering our expertise every step of the way.
I like getting out and meeting with owners early on in the project and hearing their vision.
We manage construction projects within seven distinct industries, including K12, Higher Education, Commercial, Government, Healthcare, and Aviation.
O‑A‑K understands the need to be great stewards of resources...they understand that innovation is needed to find efficiencies and flexibility is needed to meet the needs of a complex organization.
As an employee-owned construction company since the day we were founded, we are driven by the communities where we work and live. We can’t say it enough. Our people are our greatest asset.
