Deloitte’s First CMO Walks in No One’s Footsteps

Diana O’Brien, Deloitte’s first CMO, is still trying to bring disparate organizations within Deloitte together, but she’s thought a lot about data, robots, social employees and how to differentiate experiences

There’s no pressure to follow in anyone’s footsteps for Diana O’Brien. She’s taken the reins as Deloitte’s first CMO. It’s a different job than O’Brien expected, as the majority of her focus for nearly two years has been on breaking down disparate silos within Deloitte.

It seemed natural to her to bring the silos under one umbrella, O’Brien says, but, “what I didn’t appreciate when we first started was how powerful an engine we would be in championing our clients by capitalizing on the powers we have now that we’ve brought some of these groups together.”

O’Brien became CMO in March 2015 after working for Deloitte in various roles since 1985. She has pushed out new campaigns, adopted new data technologies and served as the voice of the customer in Deloitte’s C-suite. Marketing News spoke with O’Brien about her time as CMO thus far and her plans for the future.
