Fernando Quintero

In memoriam

Fernando Quintero was an invaluable member of the BMSG team for more than nine years, serving as a strategic communication specialist until he passed away on January 21, 2020, after battling cancer. No title, however, could fully capture the many ways he contributed to the world of media advocacy, strengthened our organization, and enriched the lives of those who had the pleasure of working with — and learning from — him.

During Fernando’s time with BMSG, he mentored new staff members and provided media advocacy trainings and strategic consultations for thousands of public health and social justice advocates across the country, including in California’s Central Valley, where he grew up, the child of farmworkers. As a veteran journalist who had written for several newspapers including the Orlando Sentinel, Rocky Mountain News, San Jose Mercury News, and Albuquerque Tribune, Fernando brought extensive storytelling experience and a magnetic personality to his work, which BMSG partners and clients connected with deeply. They described how Fernando “lit up the room” and created transformative experiences, helping them see their work in new ways. He used his writing and editing prowess to elevate a range of issues, from news coverage of sexual violence to strategic communication in the age of Trump, often deftly using humor to make difficult topics more approachable.

Fernando was especially passionate about exposing the manipulative marketing techniques that food and beverage companies use to target their least healthy products, like soda and junk food, to children of color. And he brought together advocates from across the country to join him in challenging such practices. When Latina singer Selena Gomez began promoting Coca-Cola, for example, Fernando opined that her new role as a soda spokesperson had broken his heart, and he helped launch a viral social media campaign, calling on celebrities to stop endorsing products that fuel diabetes and other nutrition-related diseases in Black and Brown communities. Fernando also traveled domestically and internationally to educate advocates and policymakers about the issue, testifying before the San Francisco Board of Supervisors, presenting to health officials in Mexico, and leading the target marketing subcommittee of the Food Marketing Workgroup, a coalition dedicated to ending junk food marketing to kids.

Before coming to BMSG, Fernando held many other posts: He was the managing editor of Latino.com; he served as a communication strategist for the University of California, Berkeley, as well as several nonprofit organizations and private enterprises; and he was the director of NewsWatch Project, a media watchdog organization that promoted fair and accurate media coverage of the LGBTQ community and communities of color. Despite his many professional accomplishments, Fernando was perhaps best known for his wry wit, abundant charisma, and boundless compassion. Although we lost Fernando far too soon, his spirit and his legacy live in our hearts. To honor Fernando’s memory, we will continue to champion social justice and collaborate with organizations that are working to diversify newsrooms. To learn more about this beloved member of our BMSG family and the mark he left on the media landscape, read his obituary here.
