Born on September 14, 1984, he is the only child of Marc and Suzanne Lamberg, a Jewish couple of Polish descent. A native New Yorker, he attended PS183 when he was a child. At the age of seven, he successfully auditioned for a role in a commercial from American Express. After that, he became addicted to acting. His first film roles came in 1996 at the age of eleven with I'm Not Rappaport
and Radiant City
. He was appeared in numerous Broadway plays in his native city.
His biggest role to date came when he was won a starring role in Lizzie McGuire
in 2001. Although he was fifteen years old and almost three years older than his co-stars Hilary Duff
, he was cast as thirteen-year-old David Zephyr "Gordo" Gordon. The show ran until 2004 and was cancelled after only 65 episodes.
In May 2003, shortly after the series wrapped filming, he began to attend the University of California in Berkeley, where he is still attending, as of 2006. His most recent prominent roles have been as Lionel in When Do We Eat?
and Reggie in Beautiful Loser
. As he currently both attending college and working in California, he has little opportunity to spend time in New York, much to his disappointment.
