Who we are

At 1ntegrity Construction Group, we believe there’s a better way to build.

Founded in Oklahoma City, we’re on a mission to prove that construction can be done ethically, sustainably, and without compromise—delivering high-quality projects on time and on budget every time.

We bring decades of industry experience, a commitment to transparency, and a relentless focus on doing what’s right—for our clients, our crews, and our community. From commercial developments to complex builds, we approach every project with craftsmanship, accountability, and purpose.

Integrity isn’t just part of our name. It’s the way we work.
