Because we manage all trades in-house, our timelines are shorter than most contractors. While each project is unique, many offices can be completed in just a few months from permits to final walkthrough.

While our specialty is larger, high-end dental offices, we work with practices of all sizes and budgets. Our process scales to fit your project, whether it’s five operatories or a smaller remodel.

No. We hold all necessary licenses (general building, plumbing, electrical, and MedGas) so we can handle the entire scope of the project ourselves. This keeps communication clear and avoids the delays that happen when multiple contractors are involved.
