Keranen grew up in
Oak Park, Michigan. She is of Finnish and Swedish descent through her father, who is half Finnish and half Swedish. She had always been involved in acting, including high school plays, but in an interview with Everything Geek Podcast, she said she was more active in sports. The series was broadcast on NBC for two seasons. Keranen's first voice-over audition for 4Kids was
April O'Neil in the 2003 TV series
Teenage Mutant Ninja Turtles. She landed supporting roles, and also landed some guest and supporting voices on the
Pokémon TV series. When fellow voice actress
Tara Sands moved from New York to Los Angeles, she auditioned to voice match Sands' character
Mokuba Kaiba in
Yu-Gi-Oh!. On her way out of the audition, Keranen started pitching another voice actress for the part, but director
Eric Stuart later told her that she was the right person for the role and that he even vouched for her to play the part. That was her first major role as a lead male character. Later in the same season, she also got to voice
Kisara, which she said was more typical of the characters and used her natural voice. She also voiced
Mina Simington, which she described as "type A but not in a forceful way" and would totally get into something if she had the chance. On July 23, 2011, she and fellow voice actress
Cristina Vee were panelists at
San Diego Comic-Con for Namco Bandai's preview of the
Tekken: Blood Vengeance film. In 2014, Keranen voiced
Satsuki Kiryuin, the student council president and antagonist in the anime series
Kill la Kill, which ran on
Cartoon Network's
Adult Swim. ==Filmography==
