Adam Lamberg — whom you probably know as Lizzie McGuire's David "Gordo" Gordon — fell off the radar after appearing in Beautiful Loser in 2008. That same year, Lamberg graduated from UC Berkley with a bachelor's degree in geography, and in 2012, he went on to attend Baruch College, where he got his MPA. Since then, Lamberg has kept himself busy as a developmental associate at the Irish Arts Centre in NYC. In 2014, he opened up about his decision to quit acting on Tumblr. "I finished college and figured all I really knew was acting and gave it a go after a long layoff," he said. "After a couple of early highs things have gotten tough and now I'm somewhere between the denial stage and the acceptance stage as to whether I still can/want to do this with my life." However, Lamberg is set to reprise his role in the Lizzie McGuire reboot, so perhaps he'll come out of retirement after all.
