Lea has always had a passion for performing and knew she wanted to have a career in the arts. Lea started singing and dancing in school plays and took dance lessons at a young age. Whether it was dancing in a talent show or singing in her high school musicals, she felt alive in front of an audience. Lea attended Westlake High School in Thornwood, New York where her love for theater blossomed. She continued her studies at the American Musical and Dramatic Academy which is a conservatory located in Manhattan. At school she studied with Lindsay Chambers, Ray Virta, Jeffery Dunn, and Evan Pappas.  Lea also furthered her dance training in the city at Broadway Dance Center and New Dance Group with teachers like Mark Santoro and Lainie Munro.

Lea Marinelli is trying to get her foot in the entertainment industry door like any other young performing artist. Last year, Lea was the title role in the Theaterworks USA/ Two Beans production of Alexander and the Terrible, Horrible, No Good, Very Bad Day National Tour. You also may have seen her aboard Spirit Cruise Lines in New York City. This entertainment cruise line which goes out of Chelsea Piers, hosts singing and dancing talent which she was a part of. Lea has also dabbled in the film industry. She was recently on set of the film Revolutionary Road set to hit theaters in 2008. Lea is just starting her newest project, which is taking her on tour across the U.S. and Canada for the next year. Turnstyle Entertainment is producing the musical Arthur Live! in which Lea will be playing D.W. and Ms. Tooth Decay.
