Geof Isherwood is a painter, sculptor and comic book illustrator. Born in Quantico, Virginia, he lived in Maryland, Delaware and New Jersey. Much of Isherwood's early work was done for Marvel Comics, including such titles as the Silver Surfer, Conan the Barbarian, Daredevil and others.

Influences include Gil Kane, John Buscema, Frank Frazetta, Barry Windsor-Smith, Michelangelo, Norman Rockwell and J. M. W. Turner. Since 1999, he has been involved in movies as a storyboard artist and a concepts/production illustrator, working with the likes of Bryan Singer, Richard Donner and Darren Aronofsky.

He has also painted and designed covers for Canadian publishers, including Ann Diamond's much-heralded Dead White Males (2000) and Robert Edison Sandiford's Sand for Snow (2003). A selection of his paintings based on the Greek gods were featured in Issue 59 of the publication Matrix. In 1997, he created LINCOLN-16, a science fiction saga whose first two issues he wrote, drew, painted and produced via Skarwood Productions (an amalgam of his and his wife's surnames).

Graphic novel projects underway include: Lani the Leopard Queen (a fantasy adventure for children), Erox (an adult fantasy adventure), Krugall and Glydia (a faery tale), and Krudge (a kitchen sink drama).
