About our Company

Tidewater Building Group was incorporated in 2001 by David Kreber. With an unprecedented growth in business during 2001 to 2003, David Kreber hired Zan Edens in the fall of 2004 as ownership partner and Vice President of Operations. During the challenging economic conditions from 2008 to 2011, Tidewater Building Group had to make tough personnel changes throughout the company to ensure future success for the employees, business partners, community and ownership.

On the MUSC Telehealth Project, the wall and ceiling finishes were beyond typical and required a team member that not only understood the complexities, but had the craftsmen to install it. We chose Tidewater based on this and they did not disappoint. The workmanship provided on this project was wonderful, and the owner was very satisfied and happy with the space when it opened. I look forward to more projects like these with Tidewater.

It is always great to find that Tidewater Building Group is a subcontractor on one of our projects.  I have confidence their work will be done well.  More than that, I use Zan as a resource when I have technical questions related to metal studs and drywall.  If he doesn’t know the answer, he can find the person who does.
