Former GWCC GM Mark Zimmerman to Start Consulting Firm

After more than 30 years working with the Georgia World Congress Center Authority (GWCCA), former Georgia World Congress Center General Manager Mark Zimmerman has resigned as senior business consultant for the convention center in order to devote full attention to his new business, Zimmerman Consulting, LLC. "The outlook is bright for Atlanta’s hospitality and convention industries, especially at the GWCC, but the time is right for me to focus on growing Zimmerman Consulting," said Zimmerman.
