Fellow FUNimation employee, Colleen Clinkenbeard, has stated that John is one of the best in the business and has one of the toughest jobs at FUNimation – making the translations make sense.
John was interviewed in the "North Texan Online," an online magazine for the University of North Texas, where many of FUNimation's employees have come from, including John.
John, just like fellow FUNimation employee Justin Cook, both worked on the anime Yu Yu Hakusho and voiced a main lead in it. In addition, he had to work on the script for two versions, an edited and an uncut, and dubbed it twice, once again once for the uncut and again fir the edited.
John's promotion to script supervisor came when he got the chance to write dialogue for Frieza in the anime Dragonball Z. His mother, Linda Young was voicing Frieza and after he read the script John said, "I can't have my mom reading these corny lines," and thus reworked the episodes. The success of the episodes gained him his promotion.

John wrote the English script for the anime Fruits Basket. His favorite episodes that he wrote for that series are episode 15, involving Momiji and Tohru, the Hot Springs episode, and the Prince Yuki Fan Club episodes. He stated this in an extra commentary track for the final Fruits Basket DVD.
John's favorite Fruits Basket episodes as an actor were the earlier ones where Shigure explains the story of the curse.
Due to a scheduling conflict, John was unable to attend Otakon 2004, the only convention he would have appeared at. Chuck Huber went in his place.
