Kraft Insurance reopened at their same location on 26th and Bird.
Mayor Melodee Colbert-Kean proudly attended the ceremony.
Chamber of Commerce President Rob O'Brien says Kraft Insurance continued their business by operating out of a hotel and at another temporary location.
The owners said they debated whether or not to reopen their doors but were glad they did.
"We're excited. We wanted this area to stay alive and so we wanted to make sure we are part of that," says owner Shelly Kraft.
More than 450 businesses in have been rebuilt since the tornado.
