After competing in sport karate competitions at a young age, Georges St. Pierre began his professional mixed martial arts career in 2002, defeating notable fighters Ivan Menjivar and Pete Spratt, before debuting in the UFC in 2004 with wins over Karo Parisyan and Jay Hieron. After putting together one of the most impressive winning streaks in welterweight history with consecutive demolitions of Jason “Mayhem” Miller, Frank Trigg, Sean Sherk, and BJ Penn, St. Pierre took the UFC Welterweight Championship from Matt Hughes at UFC 65 in 2006. Although he lost his first title defense to heavy underdog Matt Serra, St. Pierre reclaimed the title in a rematch one year later. He is universally regarded as one of the top pound-for-pound fighters in the world, having dismantled many of the top fighters in the division since that time, including Hughes (for a second time), Josh Koscheck (twice), Jon Fitch, Thiago Alves, Penn (for a second time), and Jake Shields.

When he first burst onto the scene, St. Pierre’s fighting style was an athletic blend of flashy striking and aggressive grappling. It was not until he refined his wrestling and Jiu-Jitsu skills, however, that he truly emerged as a world-beater. Although still considered a highly skilled striker, St. Pierre is now first and foremost known as the best functional wrestler in MMA, a truly stunning feat given that he had no amateur wrestling experience prior to entering professional fighting. St. Pierre is a relentless worker and a master strategist, often exploiting his opponent’s physiological weaknesses en route to victory. He is a humble fighter who openly and honestly discusses his mistakes in the Octagon, and who regularly travels the Americas in search of the best striking, grappling, wrestling, and MMA instruction. St. Pierre is regularly welcomed at a number of top teams in preparation for his title defenses, and carefully tailors his pre-fight camps to the opponent he is fighting.

In addition to his accomplishments inside of the cage, St. Pierre is one of the first true crossover stars to emerge from MMA, owing to an infectious natural exuberance, an Adonis-like physique, and a multi-year title reign. He is the first MMA fighter to be recognized as the Canadian Athlete of the year by Rogers Sportsnet (2008-2009), and the first fighter to be signed to sponsorship deals with sports advertising juggernauts Gatorade and Under Armour in 2009. Frequently describing himself as a "proud champion," St. Pierre is a consumate professional who takes seriously his obligations to the UFC, to MMA, and to the sponsors and fans that have made him rich and famous.
