Marnie Black
Founder & CEO, GJCA (Global Jewish
Communications Alliance)

Marnie Black has been at the heart of some of the most defining moments in media and entertainment from the last 3 decades, not just witnessing them – but making them happen. Marnie spent 30+ years developing and implementing innovative, strategic, brand-building and business-impacting public relations and marketing communications plans for media and consumer lifestyle companies including AMC Networks, MTV, Weight Watchers, HBO, Comcast, and CNN, to name a few. She was the mastermind behind countless high-profile and award-winning campaigns for groundbreaking and iconic shows including “Mad Men,” “Breaking Bad,” “The Walking Dead,” “Total Request Live” (TRL), “Real World,” “Jackass,” and “The Osbournes.” Marnie is also an expert in rapid-response crisis management and has worked on numerous large-scale crises, including Janet Jackson’s wardrobe malfunction at the Superbowl.

10/7 was a wakeup call for Marnie, whose grandparents were Holocaust survivors and whose father was born in a DP camp. In mid-2024, Marnie made a choice to leave the media & entertainment business and use her expertise building narratives and protecting reputations in service to the Jewish people. She partnered with well-known, former advertising guru, Gary Wexler, and the two formed GJCA (Global Jewish Communications Alliance). Marnie and Gary assembled 50 world class marketers who have shifted attitudes and behaviors for hundreds of global brands and who are all passionate Jews & Zionists. GJCA has been working quietly, behind-the-scenes to build a long-term strategic plan to change the narrative for Jews and decrease antisemitism over time. The goal is to utilize strategic communications to change hearts and minds over time so the future is safe for our children and grandchildren.

Marnie lives on the upper west side in NYC with her husband and two children. She holds several lay leadership roles within UJA Federation of NY.
