Greg Jackson was born in Washington, D.C. At the age of 3 the Jackson family moved to Albuquerque, New Mexico.

Greg grew up in a family of wrestlers. Greg's grandfather, uncle and brother were all wrestlers. Greg's father, uncle and brother were all champion wrestlers. Growing up in a rough neighborhood, at a young age Greg began studying martial arts. After many years of experience Greg was looking for something more. Combining basic Judo locks with his wrestling Greg started to formulate his own style and style and system of martial arts and self defense.

In 1992 Greg opened his first school. In 1993 Greg saw the first Ultimate Fighting Championship and realized that the Gracie family (which are well known for their very effective style of Brazilian Jiu-Jitsu) was much more advanced than his current ideas. Shortly after viewing the first UFC Greg started to diligently develop more techniques. Also, in 1993 Greg started training in kickboxing under his mentor Michael Winkeljohn. Mr. Winkeljohn is a 5 time world champion and is still to this day a mentor to Greg Jackson.

Greg is constantly looking for new ways to make his brand of mixed martial arts more efficient. The Jackson fighting system has been proven in both self defense and in the world of Mixed Martial Arts. To this day Greg Jackson has developed 10 world champions. His team has won such prestigious awards such as Grapplers Quest, the Pan American games and others. Jackson's fight team is also ranked number 1 in the highest winning percentage by Sherdog.com. Greg has competitors in Pride, UFC, Abu Dhabi, and many other prestigious events. Some of his top fighters include: Keith Jardine, Rashad Evans, Georges St. Pierre, Nate Marquardt, Joey Villasenor, David Loiseau, Damacio Page, Tait Fletcher, Duane Ludwig, Leonard Garcia, Julie Kedzie, and a whole host of up and coming future fight champions. Amongst some of these fighters, Greg has had competitors on Spike TV's The Ultimate Fighter, seasons 1, 2, and 3 on Spike TV.

With the Jackson camp multiplying everyday, Greg continues to live and train these warriors in Albuquerque, New Mexico with his family. In addition to being one of the most respected MMA trainers in the world, Greg will continue to build one of the largest and most prestigeous MMA schools around.
