Ron Reis was trained by Big John Studd. He made his professional debut on March 12, 1994 for the New England-based International Wrestling Federation under his birth name. In 1995, Reis began performing for the Las Vegas-based National Wrestling Conference as "SWAT".
Reis debuted in World Championship Wrestling on Monday Nitro, October 23, 1995, as The Yeti - the Dungeon of Doom's so-called "insurance policy" for the upcoming WCW World Heavyweight Championship match between Dungeon member The Giant and current champion Hulk Hogan at Halloween Havoc 1995. Initially introduced frozen inside a block of ice, the Yeti soon broke out of the ice to reveal a heavily bandaged appearance reminiscent of a huge mummy and went on to interfere in the Halloween Havoc 1995 main event, where he and The Giant attacked Hulk Hogan with a double-bearhug. Reis wore lifts in his boots at the event and had bandages wrapped high on his head, which gave the effect of The Yeti appearing noticeably taller than The Giant and caused an astonished Tony Schiavone to remark "The Yeti is taller than The Giant!". Following Halloween Havoc, The Yeti's ring attire was changed to resemble a masked ninja. However Reis only made three more appearances as the character; as an entrant in the 60-man battle royal at World War 3 1995, in a match against Barry Houston on WCW Prime, and in a match against WCW United States Heavyweight ChampionOne Man Gang on WCW Saturday Night in January 1996, where Reis' character was renamed The Super Giant Ninja. This would be the final appearance of the character. Reis later became known as Big Ron Studd in 1996, and WCW announcers billed Reis as having taken the surname of his trainer Big John Studd. Bobby Heenan, who had managed John Studd, however, disdained Ron in his column in WCW Magazine. WCW primarily used Studd as an enhancement talent. On October 21, 1996 edition of Nitro he was defeated by Jeff Jarrett. On the March 2, 1998 edition of Nitro, Reis joined Raven's Flock as Reese. Raven claimed that Reis' size had made him an outcast from society, leading him to seek acceptance within the Flock. Reis acted as Raven's enforcer, though he was unable to prevent Goldberg defeating Raven for the WCW United States Heavyweight Championship. He also suffered a loss to Juventud Guerrera at the 1998 Great American Bash. Reese's last appearance was on the June 29, 1998 episode of Nitro. Saturn pinned Reese with a Death Valley Driver.
After being released, Reis toured Japan as Big Bomb Jones throughout 2002. In 2003, he returned to America and began working for Dusty Rhodes Turnbuckle Championship Wrestling promotion, returning to the Big Ron Studd gimmick. He formed a tag team with Glacier, and they won the TCW Tag Team Championships on January 3, 2004. The titles were vacated later that year. Reis reemerged in Vince Russo's Christian-orientated Ring Of Glory Wrestling promotion in 2005 as the abstract character Evil, losing to Joshua the Carpenter on February 26.
