Here's a short Mini Bio that I found awn IMDb. Elizabeth McLaughlin is THE ah-mazin girl that plays Massie Block.
Elizabeth McLaughlin began her acting career with community theatre groups in Tampa, Florida. At eight years old, she joined the apprentice cast of Entertainment Revue, a professional show choir in Tampa, and was promoted to the professional cast two year later. Performances have included singing for Gov. Bush and Schwarzenegger. Elizabeth is an honor student, has won several speech and storytelling competitions, and was a cheerleader at her former high school.
