Silberberg received a bachelor's degree in international relations and history from American University in Washington, DC, and a master's degree in fine arts in playwriting from the School of Theater, Film and Television at the University of California, Los Angeles. Silberberg is the author of “Visionaries in Our Midst,” a book that profiles individuals making a difference in the United States. She is also the author of “And Life Will Be a Beautiful Dream,” a commissioned memoir about the meaningful life of a philanthropic family. She wrote an episode for the situation comedyMama's Family, titled "Mama's Layaway Plan." It debuted on February 11, 1989. She has also written columns and articles for PBS, The Washington Post, and The Dallas Morning News''. Silberberg has over 25 years of experience in community leadership and public service, including interning for Senator Ted Kennedy and working for Senator Lloyd Bentsen. She served a three-year term on the World Bank's Community Outreach Grants Committee, which disbursed major funding to local nonprofits in Washington. She started and led a nonprofit called Lights, Camera, Action!, which used film to mentor youth in Anacostia. For nearly a decade, Silberberg hosted monthly charitable events, which gave all proceeds to local nonprofits focused on children at risk and families in distress. Silberberg has lived in Alexandria since 1989. From 2004 to 2012, she served on Alexandria's Economic Opportunities Commission, which advocates for the city's most vulnerable residents. As chair of the EOC, she initiated the EOC's annual public service day, “All Hands on Deck.” The first annual “All Hands on Deck” renovated the Alexandria Community Shelter with the help of 100 volunteers. Silberberg won New Hope Housing's 2012 Leadership/Servanthood award for her role in leading the “All Hands on Deck” project. In 2012, she was elected to the Alexandria City Council. Because she won the most votes of all the candidates, she became the city's Vice Mayor. In 2015, Mayor William D. Euille, Alexandria's first African American mayor, lost the Democratic primary to Vice Mayor Silberberg. He then ran against Silberberg as a write-in candidate, but to no avail. Silberberg was sworn in on January 4, 2016. Silberberg was defeated in her bid for re-election by Alexandria Vice Mayor Justin Wilson on June 12, 2018, in Alexandria's Democratic mayoral primary.
