Born in Italy, Sofia moved to the United States with her family when she was two years old. She was born to a British mother and Italian father and is the youngest of three girls. Sofia discovered her love for the stage when she started taking dance lessons in third grade; she ended up dancing for 9 years. However, it was being cast in the part of Sharpay in High School Musical in her middle school play that made her realize she loved theatre even more than dance. She continued doing musical theatre for the next 6 years. During her senior year, she was signed by an agency and started pursuing TV/Film. She started, and continues to, train weekly. She can be seen in IFC's Stan Againt Evil and FOX's The Gifted.
