She has two siblings; an older brother named Todd, an actor and avid cyclist, and a younger brother named Schuyler. Her father is of German descent and her mother is a mix of Greek, Turkish, and Welsh descent. She credits her brother, Todd, as one of her most important sources of inspiration, and her mother and grandmother as role models.
