Stephens started the new role on January 4, after leaving her position of project manager at Primary Live, a role she held for almost three years.
She has now joined Noble's automotive team, following a successful year for the company.
Penny Noble, managing director of Noble Events, said: "We're delighted to have Katie onboard to work on a key automotive account. I've known her for many years, working together in previous roles, and she will make a great addition to the team."
She added that the business expanded in 2015, with significant growth on key accounts and a new client win. "We're expecting another busy and succesful year ahead, with further growth and development in the pipeline," she added.
