Carpenter is most recognised for his work on the hit WB television series 7th Heaven, in which he played a significant role in the 1998-1999 season. His character was the subject of much debate as he dated both sisters (played by Jessica Biel and Beverly Mitchell), with the season ending amidst this controversy. He also made a guest appearance on the show Providence.
Carpenter's feature film credits include Dirt Merchant, All the Little Things, and Hymn.
Carpenter is also the front man for his band, Triple Fix, an emerging rock and roll band currently playing in the Los Angeles club circuit.
