Firm Profile

Since its founding in 1990, MBI Companies, Inc. (MBI) has been committed to being the top architectural, engineering, and interiors firm in the markets we serve.  We do this by hiring the most talented and highest integrity people, by being the leader in technological innovations and expertise, by being attentive listeners and problem-solvers for our valued clients, and by creating and executing some of the best-designed projects in our region.
Our staff of over 90 professionals maintains licensing in all 50 states, out of our offices in Knoxville and Chattanooga.  MBI has three LEED Accredited Professionals on staff with diverse project experience and is an Energy Star Partner design firm.
We are able to save our clients both time and money by streamlining the design process and by utilizing advanced technologies such as Revit 3D Building Information Modeling software for Construction Document production, allowing clients to actively participate in the design process via 3-Dimensional images.
Most importantly, we do what we say we will do – every time.  Our clients can count on us to keep our promises and to meet their deadlines.  MBI focuses on listening to what matters most to our clients, with our over-riding goal being to delight them with the most innovative design solutions possible and to exceed their expectations in every phase of the project.
