Greenlight strengthens social media offering with new appointment

Greenlight has seen the number of clients which it offers social media optimisation services to grow, and O'Brien will head up the integration and expansion of the agency's current offering.

O'Brien joins the company from Citibank, New York, where she served as vice president of social media and created the initial roadmap and strategy for its social media presence, integrating social technology into various aspects of the programme.

During O'Brien's tenure, Citi became the first financial services account verified by Twitter and the first to have a custom URL shortener. O'Brien also initiated and led the bank's robust listening programme.

O'Brien is an internationally recognized speaker on the social media circuit. Events she has been invited to speak at include SXSW, eMetrics, Social Media Week (New York) and Social Media Insider Summit.

O'Brien is listed in AdWeek's top 25 advertising professionals on Twitter. Her appointment will see Greenlight gain valuable expertise in the social media field thereby bolstering the firm's social media optimisation assets.

Andreas Pouros, chief operating officer at Greenlight comments: "Anna's appointment places Greenlight immediately at the top of the social media marketing arena, firmly transforming the agency into a leader in the engagement marketing space. This is an exciting time for Greenlight."

Prior to Citi, O'Brien worked with Critical Mass and Wunderman.

O'Brien holds an MA in quantitative methods in the social sciences with an emphasis in new media measurement, from Columbia University.
