Jeri Kalvan’s career in acrobatics and stunts began as a small child when she was inadvertently dropped on her head. As a teenager she competed in elite gymnastics, and she also excelled at many skills, including skydiving, cliff jumping, and barefoot waterskiing. Jeri Kalvan holds a masters degree in Curriculum and Instruction. For ten years, she enjoyed teaching movement and circus to elementary school children, motivating them to learn difficult skills and create group performances.

In 2000, her brother, stunt coordinator Jeff Habberstad, assisted her entry into the film industry, where she met success as a stunt actor, stunt double, and stunt coordinator.
