Elliott Davis Decosimo is moving its offices into the Miller Building at Broad and Seventh streets. The firm has been located for more than 30 years a few blocks away at Tallan Financial Center at M.L. King Boulevard and Carter Street.

“It’s going to be exciting,” said Nick Decosimo, the company’s Chattanooga office managing shareholder. “The young people are excited. We’re moving into an old building, but you can do great things with a blank slate.”

The accounting firm will occupy more than 40,000 square feet in the historic Miller Building, which dates to 1898.
