Services will be held Saturday for Matthew J Brennock, managing partner/executive creative director at Momentum Worldwide and widely acknowledged as a great creative mind, who died, suddenly, in  May at age 52.

Momentum chairman/CEO Chris Well said of Mr. Brennock, “We are tremendously saddened by the news of Matt’s passing.  No words can do justic to the impact he made on Momentum Worldwide, because words can’t capture how great a friend he was to all of us.

“He wasn’t a coworker, he was a family member and a brave, honest, brilliant, unforgettable person.  He was a family  man and a mentor, and a coach and a fierce warrior for the new and the different.  We all miss him.”

Over his 25 years in the Chicago advertising industry, starting at DDB for six years rising to VP/CD. He then spent two years at J. Walter Thompson as SVP/GCD and in 1998 joined Michael Oberman as a partner in Fusion Idea Lab.

“Matt was a brilliant writer, a great guy with a big heart. He was a wonderful mentor to young writers,” recalls Oberman who first met Mr. Brennock when both were starting their careers at DDB. 

“He was a great presenter as well. When he was on, the clients were spellbound. Advertising in general has lost a very smart-thinking creative mind.”

After 11 years at Fusion Idea Lab, Mr. Brennock moved to New York to work for Digitas as SVP/creative strategist and new business strategist.  A year as SVP/content architect and business development at IPG Media brands, also New York, led to his return to Chicago as managing partner of the Chicago office of Inter Public’s Momentum Worldwide network.

Over the years he worked on such diverse clients as Anheuser-Busch, McDonald’s, Kraft, Expedia, Orbitz, New Line Cinema and Target.

Mr. Brennock is survived by sons Ashlan and Peyton, his mother, four sisters and his ex-wife.
