Jeff "Swampy" Marsh left a corporate job to pursue art. Three months later, he found himself learning animation by drawing backgrounds for a fledgling show in its second season called... The Simpsons. After trying for over ten years to get it on the air, he and his creative partner Dan Povenmire got their dream show on Disney, Phineas and Ferb. Spoiler alert, people liked it. A LOT. 

Besides now acting as the showrunner for Pete the Cat on Amazon Prime, Swampy also devotes a lot of time to a charity called "A Walk on Water," which provides surf therapy to children with special needs and their families. 

A new Pete the Cat Christmas Special arrives on Amazon this Tuesday, November 20th.
