The last person to hold that position was Rosemary Gorman, who left to become advertising director at The Evening Standard in June 2006, replacing Alan Brydon. Bromley will report to ad director John Teal.
He will be responsible for a team of three client sales managers: Andy McDouall, Lorraine Keogh and Brad Young.
Prior to working at the NMA, Bromley was worldwide managing partner at MindShare.
