Karen J Green

Karen was the loving sister of Howard (Rosemary) Green, the late Michael J. Green, and the late Susan C. Green; daughter of the late Rose and Jules Green; dear aunt to Jennifer, Kailey, Ava; cherished partner of David Zisman, step-mother to Jodi (Jeremy), Randi (Greg), grandmother to Quinn, and last, but not least, dearest companion to Remi, her cat.

Karen passed away after a remarkable life defined by intellectual curiosity, creative leadership, and deep human insight. Born in Miami and raised in Chicago, Karen pursued her education at the University of Illinois, earning multiple degrees with honors before continuing her studies in psychotherapy at the Alfred Adler Institute of Chicago. Her early years reflected a lifelong curiosity about people and the world—living on a kibbutz in Israel, working in the psych ward at Guy’s Hospital in London, and later establishing a private psychotherapy practice in Chicago.

Karen’s career took a pivotal turn when she joined the Leo Burnett Company, where she would spend nearly four decades shaping some of the most iconic brands in the world. She began her advertising journey on the Philip Morris business and went on to play a defining role in articulating the Marlboro brand’s essence—work that continues to influence the industry today. Over the years, she contributed to a wide range of global brands, including Virginia Slims, 7UP, Procter & Gamble, Nestlé, Hallmark, McDonald’s, and Disney, among many others.

A visionary thinker and passionate advocate for strategic excellence, Karen founded the Idea Lab, co-founded the Global Planning Standards Board, and was a co-author of the original “4C’s,” helping to shape modern planning practices. She was also a certified executive coach, mentoring and inspiring generations of colleagues. Karen was known not only for her formidable intellect and creative force, but also for her wit, warmth, and unmistakable presence. She challenged those around her to think more deeply, pushed ideas further, and brought humor and humanity into every room she entered.

Beyond her professional accomplishments, Karen remained devoted to her psychotherapy practice, her love of travel and culture, and the people closest to her. She is survived by family and friends, who will remember her for her sharp mind, generous spirit, and the joy she brought to their lives. Karen Green leaves behind an enduring legacy in both the worlds of advertising and human understanding—and will be deeply missed by all who had the privilege to know her.

Services will be private. A memorial service honoring Karen will be held at a future date.
