Olsen has appeared in over 100 roles since 2005. Many of these are supporting roles, which she credits as allowing her to work on more projects than actors who focus primarily on leading roles. She says her favorite roles have been in African Gothic, Percy Jackson, Die-ner (Get It?), The Haunting of Whaley House, and Live-In Fear, which was the first film she produced.
In 2011, she founded the production company MOnsterworks66.
