Cassidy's remarkable journey in the entertainment industry began at the tender age of 14, when a discerning talent agent in Florida stumbled upon her extraordinary talent and offered her a chance to pursue a career in modeling and acting, starting with commercials.
This initial exposure led to a prestigious one-year scholarship at the esteemed Huntington Film Institute in Orlando, where she honed her craft and laid the foundation for her future success. Her impressive talent and dedication caught the attention of the producers of the popular Nickelodeon series "Clarissa Explains It All," who cast her in a pivotal role in 1991.
As her star continued to rise, Cassidy made the bold decision to relocate to Los Angeles with her mother, Amy, in 1993, to pursue her dream of becoming a successful actress. This marked a significant turning point in her career, as she began to land more substantial roles and make a name for herself in the competitive world of Hollywood.
Her first on-screen appearance was in the TV show "Angel Falls" in 1993, a role that showcased her impressive range and versatility as an actress. She then went on to star in the short-lived but critically acclaimed Spelling show "Models Inc." in 1994, cementing her status as a rising star in the entertainment industry.
