Goldberg was born in Springfield, Ill., and grew up playing volleyball and performing in local productions like the Chicago City Ballet's Cinderella. She earned a bachelor's degree in biology from Amherst College in 1996, and had dreams of becoming a doctor before she started acting.

Goldberg got her start in acting after appearing as an extra in the 1997 Julia Roberts film My Best Friend's Wedding, and then moved to California. She appeared on several TV shows, including House, CSI and a recurring role on Judging Amy, but it wasn't until she landed the role of Sarah on 7th Heaven that Goldberg really found success.
