In 20 years at ATL, Elizabeth Horton went from cleaning glassware and washing hair to Executive Vice President. Her success hinged on one simple thing: she didn’t wait for opportunities, she pushed for them. She did whatever was needed at the time and she never said “no.”


Technical career track | People management career track

ATL is a springboard for your professional future, not a quick career stop. We prefer to promote from within, so part of every manager’s job is to identify and grow talent within their group. Whatever path you want to pursue, whichever challenges you want to tackle, we have a plan.
