Universal Vale Tudo Fighting

Bobish made his professional debut on October 22, 1996 in Brazil at the Universal Vale Tudo Fighting 4 Heavyweight tournament. He first faced Brazilian jiu-jitsu fighter Mauro Bernardo, whom Bobish defeated in a first-round submission by taking him down and choking him with his forearm. The American would find another wrestler and UFC veteran in the second round, Dave Beneteau, but Bobish controlled the bout with a guillotine choke with several strikes, eventually getting the win by a cut.^[6] He then fought yet another wrestler and UFC veteran, fellow NCAA collegiate champion Kevin Randleman from Team Hammer House, for the final. Bobish controlled the first minutes from the clinch, attempting neck cranks and landing several punches, but Randleman escaped. The two then exchanged hard strikes, with Bobish getting the better of it, but Randleman scored a takedown and mounted him, from where he landed several strikes.^[6] Two of the hits dislocated Bobish's jaw, forcing him to give up.^[5]

After the defeat, he returned to United States and joined Severn's team full-time, training with him, Don Frye and shootfighting teacher Becky Levi.^[6]

Bobish returned at Vale Tudo Fighting 6 tournament, knocking out Ucimar Hypolito in six seconds in order to meet regarded Carlson Gracie's trainee Carlos Barreto in the semifinals. Again, the American wrestler controlled most of the bout, taking down and hitting ground and pound on Barreto via his superiority at the clinch. Controversy arose at one point, as Barreto's teammates Wallid Ismail and Murilo Bustamante claimed Bobish had tapped out in an armbar attempt by Barreto, while Hammer House stablemaster Mark Coleman pointed out Carlos was grabbing the ropes to avoid being taken down. In any case, minutes later Bobish started to show fatigue, and when he dove again in Barreto's guard to continue his ground and pound assault, he fell to a triangle choke submission.^[6]

Ultimate Fighting Championship

After his vale tudo tenure, Bobish debuted in Ultimate Fighting Championship in 1997, following the tenures of Severn and his other teammate Don Frye. He entered the UFC 14 heavyweight tournament, where he was placed against kickboxer and UFC veteran Brian Johnston. Although his opponent proved his field of expertise by momentarily stunning Bobish, the wrestler took him down, folded him against the fence and submitted him to a forearm choke. Bobish advanced round and met another Hammer House fighter, fellow former NCAA Division I champion Mark Kerr, who opened their match with effective leg kicks and a takedown scored. Bobish tried to escape, but Kerr held him down while hitting ground and pound, and ultimately jammed his chin into Bobish's eye to force him to give up.^[7]

King of the Cage

After moving to 6–3, Bobish fought Eric Pele at KOTC 12: Cold Blood for the vacant KOTC Super Heavyweight Championship. Bobish won after Pele's corner threw in the towel at 1:10 into the second round.

Bobish then defended his title against Mike Kyle, before losing it to Jimmy Ambriz at KOTC 16: Double Cross.

PRIDE Fighting Championships

Following his professional wrestling work in Japan in 2003, Bobish had his first MMA bout in Japan for event X-1, easily defeating Basil Castro. He was then brought to PRIDE Fighting Championships in November, pitted in PRIDE Final Conflict 2003 against renowned UFC and PRIDE veteran Gary Goodridge. However, the bout was short and controversial: having received an eye poke in the first striking exchange, Bobish stopped fighting and told the referee on the belief the match would be stopped for the ring doctor, but it wasn't, and Goodridge capitalized on the distraction to knock Bobish out.^[8]

Bobish returned at PRIDE 27 against feared Ukrainian striker Igor Vovchanchyn. The American scored an early takedown and mounted Vovchanchyn, initially looking for a neck crank and later seeking a keylock, while applying ground and pound during the process. Eventually Vovchanchyn regained guard, and action was restarted on the feet with a yellow card for Bobish due to a lapse of inactivity. Vovchanchyn then landed multiple strikes while on the feet, but Bobish managed to take him down again and achieve north/south position, ending the round with another submission attempt. At th second, however, Vovchanchyn controlled an already visibly tired Bobish with punches and knee strikes, and ultimately dropped him and mounted him for his own ground and pound. Devoid of energy, Bobish then submitted verbally.^[9]

Bobish then faced another renowned kickboxer in Mark Hunt at PRIDE 28 on October 31, 2004. Bobish scored a takedown and forced Hunt to turtle up, landing hammerfists and knee strikes and at one point even attempting a crossface hold on the kickboxer. However, the tough Hunt absorbed the damage and managed to escape to his feet. With Bobish showing signs of fatigue, Hunt forced him to surrender with an uppercut and a body kick.^[10]

Independent promotions

After his PRIDE run, Bobish returned to King of the Cage, and regional U.S. promotions. He went 8–2 in his final ten fights. He lost his last fight at Hardcore Championship Fighting: Title Wave against Alexander Emelianenko on October 19, 2007. During the fight Bobish blew out his L3 and L4 discs in his back, and made the decision to end his career rather than receive surgery.
