MDC Partners' KBS has named Chief Strategy Officer Jonah Bloom and Chief Information Officer Matt Powell as co-presidents of the New York office. They will also continue in their current roles.

Mr. Bloom and Mr. Powell assume responsibilities that had been handled by Ed Brojerdi, who was promoted to CEO of the New York office last month from president and co-chief creative officer there as agency CEO Lori Senecal moved up to president-CEO at MDC Partner Network and Global Executive Chairman at KBS.

Mr. Bloom, a former editor of Ad Age, joined the agency in 2011 as executive director-content strategy and later co-founded KBS's Content Labs. He was named chief strategy officer in 2012.

Mr. Powell came to the KBS in 2008 as director-new business and later helped start KBS's creative technology arm, Spies & Assassins. Spies & Assassins provides development capabilities for the agency's digital production, including areas such as hardware and prototyping.

Mr. Bloom and Mr. Powell will report to Mr. Brojerdi.
