Greg Warren

Greg Warren recently released his special The Salesman, co-produced by Nate Bargatze and 800 Pound Gorilla Media. The project tells the story of his post-college phase when he had a stint selling Jif and Pringles for Procter & Gamble which eventually led to his decision to become a full-time comedian. According to The New York Times, Greg “…has done for peanut butter what Jerry Seinfeld did for Pop-Tarts and Jim Gaffigan did for Hot Pockets.” An honest mix of self-deprecation, frustration and an arsenal of lifelike characters highlight Greg’s colorful perspective.

He can be seen in his Amazon Prime Special, “Where The Field Corn Grows”, Fish Sandwich on Dry Bar Comedy, Late Night with Seth MeyersThe Late Late Show and Comedy Central Presents. Greg attracts a diverse audience spectrum, having performed as a finalist on BET’s Coming to the Stage and on Country Music Television. He is a favorite on the nationally syndicated Bob & Tom Radio Show, which led to touring theaters nationwide with The Bob & Tom All Stars Comedy Tour. Greg’s comedy has been a daily staple on Sirius/XM’s Laugh USA and Jeff and Larry’s Comedy Roundup channels for a decade. You can hear him guesting on
podcasts like Nateland, Never Not Funny, Bertcast, Dumb People Town, The Adam Carolla Show and many more. He’s performed as a New Face of Comedy at JFL, on Comedy Central’s Premium Blend and NBC’s Last Comic Standing.

Greg hails from St. Louis, MO, where his father was a high school wrestling coach and his mother made him play clarinet in the band. He has captivated audiences with anecdotes about the conflict inherent in meshing the two disparate high school identities of varsity wrestler and band geek. Greg was also a West Point Cadet, where he distinguished himself by amassing an impressive tally of demerits and endless hours of pointless marching. After moving on to the University of Missouri, he studied journalism and became an All-American college wrestler.
