Construction that minimizes disruption in the workplace.

Cowen Tenant Improvement has been renovating buildings for our clients for 125  years.

One of our very first projects when we converted a bank into a hotel right here in Shawnee. Other notable projects include a 50,000-square foot call center we completed in 75 days, as well as a landmark project on the “Mansion House” in downtown Tulsa where we completed a complete interior and exterior renovation and restoration.
