Wendy Clark, Chief Executive Officer of DDB North America, stated, “Mark’s unique background, anchored in traditional creative excellence and most recently extended into data-driven media thinking across the customer journey, makes him the perfect leader for Unlimited as we move into phase two of the company’s development. At the same time, we want to thank Brian enough for the contributions he’s brought to the table during phase one of Unlimited’s journey.”
