Thanks for stopping by! We’re pleased to announce that Rentenbach Constructors Incorporated is now officially known as The Christman Company. Christman acquired Rentenbach in a merger of the two privately-held firms in December 2013 and the company’s Knoxville, TN and Greensboro, NC offices continued operating under the Rentenbach name for several years but are now moving forward under the Christman brand.
