After watching Royce Gracie from Brazil's Gracie Jiu-Jitsu totally dominate any black belt or pro fighter at the first UFC (Ultimate Fighting Championship), a no-holds-barred competition, Tery started training in the only Jujitsu school in his area. Mr. Corkran received his black belt in 1996 in Japanese Jukido Jitsu.
In November 1995, Tery found out that instructor Carlos Machado, the multi-world Brazilian Jiu-Jitsu champion, fifth degree black belt, and cousin to the legendary Gracie's, had moved to Dallas and was teaching at Chuck Norris's Walker Texas Ranger studio. Tery began training with Mr. Machado right away. He is now a fifth-degree black belt and continues to train under Carlos Machado. He is also continuing to train in American kickboxing and Muay Thai kickboxing.
Tery has competed in several Brazilian Jiu-Jitsu tournaments, Tery won 3 gold medals in the 2001 and 2002 Brazilian Jiu-Jitsu Pan American championships in Florida this event in the US was comparable to the Worlds Championship because the worlds was only held in Brazil at this time. He received his black belt from Carlos Machado on October 19, 2002. Tery was one of 8 black belts living in the state of Texas, and one of 20 Americans living in the U.S. at that time. Tery tries to associate himself with teachers that are well-known for their talent and proving themselves in competition as world champions, such as Carlos Machado and his brothers.
