Geoffrey "Geoff" Lazer Ramsey is a renowned American voice actor and comedian. He co-founded the production company Rooster Teeth in 2003 and is best known for voicing Dexter Grif in the long-running web series Red vs. Blue.
Geoff is also a voice actor, Internet and YouTube personality, producer, and actor for Rooster Teeth. He co-starred in the first season of animated web series X-Ray and Vav and co-starred in the bi-weekly reality series Happy Hour alongside his then-wife Griffon Ramsey and friend Gavin Free.
Born on June 19, 1975, in Alabama, Geoff grew up primarily in Mobile, Alabama, and later in Florida and the outlying areas of New Orleans. He was a semi-pro bowler in his teenage years and enlisted in the United States Army while in high school, serving from 1993 to 1998.
After his military service, Geoff secured a job at the tech support company TeleNetwork Partners, where he met Burnie Burns. Prior to working for Rooster Teeth and TeleNetwork, Geoff worked as a production assistant for View Askew Productions and as a roadie for the band Catch 22.
Geoff co-created the web site drunkgamers.com with Gus Sorola and hired Burns shortly afterwards to run the site. He started Rooster Teeth Productions with his friends, Burnie Burns and Gustavo Sorola, and became an Internet celebrity, regularly showing up at conventions such as PAX and Comic-Con.
While working at Rooster Teeth, Geoff co-created the Red vs. Blue series in 2003 and the Achievement Hunter series in 2008. He frequently worked with Sorola and Burns on the Rooster Teeth Podcast, previously known as "The Drunk Tank".
Geoff also works on series such as Achievement Hunter, which he started and ran, with his usual co-host Jack Pattillo. They show people how to earn Xbox 360 achievements and focus on the most difficult or confusing achievements to get. They then created a weekly update/news show called Achievement Hunter Weekly Update (a.k.a. AHWU).
At some point, Geoff and Jack created a game through Halo: Reach's Forge mode called Achievement HORSE, similar to the basketball game horse. This series came out every Wednesday, where gamers sent in maps they had created and Geoff and Jack played them. The first to complete the map wins while the other loses.
In addition to Achievement HORSE, Geoff and Jack started the very popular Fails of the Weak series, where fans could send in funny or interesting video clips containing gameplay footage from Halo games. Each Friday, Geoff and Jack organized a montage of fails and narrated them with their usual antics.
Ramsey is one of the original voice actors for Rooster Teeth's sci-fi comedy machinima series Red vs. Blue (as the voice of Dexter Grif) which premiered in 2003. He has gone on to become an Internet celebrity, regularly appearing at conventions such as PAX and Comic-Con.
He took a years-long hiatus from the podcast after September 2011 before returning. Ramsey's other work with Rooster Teeth includes voicing The Omnipotent Voice in the machinima series The Strangerhood (2004-2006),playing a fictionalized version of himself in both Captain Dynamic (2008) and Rooster Teeth Shorts (2009-present),being a "lab rat" in Immersion (2010) and voicing the Copirate, the primary antagonist of the animated series X-Ray and Vav (2014).
In 2008, Ramsey started Achievement Hunter with colleague Jack Pattillo, a department of Rooster Teeth Productions centered largely on video games. Achievement Hunter originally consisted only of Ramsey and Pattillo, but now has thirteen members.
Geoff lives in Austin, Texas, with his family, his wife Griffon Ramsey (born E. O'Connell) and their daughter Millicent "Millie" Ramsey. He and Griffon divorced in 2018, and Geoff now lives with his girlfriend.
