KBS Makes a Trio of Executive-Level Promotions

By Erik Oster 

MDC Partners’ KBS (formerly Kirshenbaum Bond Senecal + Partners) promoted Katie Klumper to president of its New York offices, Jonah Bloom to global chief strategy officer and Matt Powell to global chief technology officer. The changes will not affect the role of KBS director of global business leadership Steve McCall

The series of promotions follows Stanley Black & Decker consolidating its digital account with KBS earlier this month following a review.

Klumper receives the promotion from her previous position as president of business leadership, a role she has held for the past year, following three years as a group account director. She originally joined the agency two years prior to that as an account director, after four years in that role with Cossette New York, working with clients such as Penguin Books, McGraw-Hill and Business Week. Before Cossette she served for a year as an account executive with Grey, working with Starbucks and HMSHost and then for a year with MacLaren McCann, working with Electronic Arts, Matterhorn Ice Cream Group and Province Newspaper Group. 


Bloom receives the promotion to global CSO from his previous role as co-chief strategy officer and co-president New York, a position he has held since joining the agency in January of 2011. He was also the co-founder of the agency’s kbs+ content labs. Before that he spent a year and a half as CEO and editor-in-chief of Breaking Media, after over seven years as an editor for AdAge (we forgive him).

Powell previously served as Chief Information Officer and co-president, New York, a role he began in early 2012 following two years as executive director of creative technology. He arrived at the agency six months earlier as director of marketing technologies, following a year and a half as vice president, director, business development and digital strategy with Company C.

KBS is still searching for replacements for its co-chief creative officers Dan Kelleher and Jonathan Mackler, who left the organization back in January. Kelleher later became CCO at Deutsch New York.
