Early life

Born on September 21, 1983, in the quaint town of Rhinebeck in Dutchess County, New York, Joseph Francis Mazzello III was raised in the town of Hyde Park. The Mazzello household, run by Virginia Strong and Joseph Mazzello Jr., was a nurturing environment for creativity, thanks to their dance studio business.

Joseph’s foray into the world of acting began during his educational years, making his first appearance in the cinematic world with a minor role in “Presumed Innocent.” This 1990 film featured heavyweights like Harrison Ford, Raul Julia, and Brian Dennehy. His acting caught the eye of none other than Steven Spielberg, who played a pivotal role in setting the trajectory for Joseph’s future career in the entertainment industry.
