The Story

Jen Costillo is an American-born Latina. Her vocal ranges between confident and informational to quirky characters. Her voice has been described as a bit raspy, confident, authoritative, wry-wit, straight-forward, with the occasional international accent. She enjoys creating new characters ranging in both age (young girls 8+ through late 50’s) and location (Brooklyn, Mid-Atlantic, Eastern European and beyond). Her smooth delivery has been used in meditation.

Consider Jen, your friendly techno hacker. As an electrical engineer and host of a hardware hacker podcast ( , she is comfortable with delivering highly technical material including medical narration and e-learning.

Her extensive background in dance (ballet, contemporary, and modern) as a dancer and choreographer in addition to fitness training is ideal for health and fitness narration.
