Personal life

Semi Chellas is now based in Los Angeles, where she lives with her partner, writer-director Mike Goldbach, and their two children.

Her interest in social change fuels much of her writing, including her Emmy nominated work on Mad Men, and her directorial debut American Woman. Her writing is influenced by social issues and themes that are pervasive in society, in particular sexism, racism and political activism. She is a supporter of Black Lives Matter, having witnessed the protests that took place outside her home in Los Angeles during the pandemic in 2020. This stems from her upbringing by parents, who were very politically engaged, and this influenced her own passion for activism.[9] A theme in her dramatic writing is people's struggle to change.[10]
