He is the official voiceover to Jason Earles, Doc Shaw, and Andrew Garfield. He also voices various characters from "Pokémon", Flash Sentry from the "My Little Pony" series, Donatello from the 2012 "Teenage Mutant Ninja Turtles", Heath Burns from "Monster High", and "Babel II".
- Thomas (Hero of the Rails - The Great Race, excluding Thomas the Babysitter and the twentieth series)
- Edward (Victor Says Yes and The Missing Christmas Decorations; only one phrase as an error)
- Percy (Hero of the Rails - The Great Race, excluding the twentieth series)
- He left the cast because the dubbing company was paying 3% less money, similar to Martin T. Sherman who left the US cast for the same reason.
- He, Héctor Ireta de Alba and Martin Sherman are the only actors to have voiced both Thomas and Percy.
