Ramos was born in Los Angeles, California, of Hispanic and Jewish descent. She became very interested in acting at a young age. "According to her mother, 11-year-old Sarah Ramos would go to bed each night pleading to get an agent — then wake up each morning asking about the status of her parent's talent agent search."
Ramos was nominated for three Young Artist Awards; in 2003 for "Best Television Ensemble", in 2004 for "Best Young Actress Under 10, Television Drama", and in 2005 for "Best Supporting Actress, Television Drama or Comedy" for her work in American Dreams.
In 2003, she won "Best Actress, Television Drama" from Women's Image Network. In April 2006, she landed the role of Hannah Rader on the CW series Runaway'. However, the show was canceled after one season.
In 2009, she was cast as Haddie Braverman in the NBC series Parenthood.
