Born 20 October 1977, Witwer was a big fan of Star Trek: The Next Generation as a child, and went on a tour of the set. The tour guide took him and his brother to meet Wil Wheaton (Wesley Crusher), who was studying in his trailer. Witwer said Wheaton "talked to us for 30 minutes, while the rest of the tour group just sat by and patiently waited. That experience put it in my head that I wanted to be an actor". 
Witwer was willing to leave the show of his own accord because of other work possibilities in Los Angeles. Currently, he is producing, writing, and directing an independent film, and hopes that several other Battlestar Galactica cast members and fellow friends, like Nicki Clyne, might be able to make cameos.
Witwer remained a fan of Star Trek and appeared on Enterprise in the episode "The Shipment" as a Xindi-Sloth because he asked his agent to find a role for him on Star Trek, and as an unpleasant result Witwer said that "I’m affectionately referred to, by my other friends that work on Star Trek, as Sam the Sloth, which totally sucks."
Witwer's true passion is his band, the Crashtones, a one-man band with Witwer performing all of the instruments and vocals. To achieve the illusion of having multiple people as his band, Witwer dresses up in costume as various fictitious other members of the "band", who appear on the cover of "their" albums.
