Gregory "Greg" Abbey is an American actor and voice actor, currently voicing characters in the English-language dub of the Pokémon anime. He is sometimes credited as Frank Frankson or John Campbell.
Abbey was born on December 15, 1970, in Great Falls, Montana, but he spent his childhood moving around the United States due to his parent being in the Air Force. He graduated from Rutgers University as an adult and pursued a voice acting career afterwards. Abbey began to provide voices for the Pokémon anime around the sixth season. He provided the voice of Scott in The Scheme Team, Numero Uno Articuno and The Symbol Life, as well as several additional roles until Pokémon USA and TAJ Productions took over the dubbing and distribution of the series. He later returned to the series in Hot Springing a Leak!.
