Katie Leigh
I'm not a teenager in real life, but I play one on the radio!
Katie Leigh is an American voice actress, most active in the 1980s but continuing to play a number of roles today. Her most enduring role, though not her most notable (at least to fans of televised animation), is as the character Connie Kendall on the Christian-themed radio program Adventures in Odyssey.
As far as television is concerned, Katie Leigh is probably best known for her roles as Rowlf the Dog on Muppet Babies and Alex during the first two seasons of Totally Spies!. Her other roles include appearances in the Dungeons & Dragons animated series, Gummi Bears as Sunni Gummi, My Little Pony in a number of roles, Darkwing Duck, and a number of others. She's also done voices in a number of video games, including Grim Fandango and Star Ocean: First Departure.
