Shawn Tompkins (March 16, 1974 – August 14, 2011)[2] was a Canadian kickboxer and mixed martial artist, and later trainer.

He later relocated to Las Vegas, Nevada in the United States in August 2007 and worked as the head striking coach at Xtreme Couture Mixed Martial Arts before joining the Tapout Training Center in October 2009.

Tompkins taught such notable fighters as Vitor Belfort, Mark Hominick, Chris Horodecki, Wanderlei Silva and Sam Stout.

The gym saw great success during this time with Team Tompkins holding two belts in TKO/UCC at Lightweight and Featherweight, with a combined total of 11 title defenses between Mark Hominick(7) and Sam Stout(4).

[15] The gym in its current form emerged in 2012,[16] founded by three of Tompkins' star pupils Mark Hominick, Sam Stout, and Chris Horodecki,[17] who went about training the next generation of mixed martial artists out of the newly rebranded Adrenaline MMA Training & Fitness.

[18] During this period, Adrenaline talent Chad Laprise embarked on an 7 fight win streak to earn himself a spot on the UFC's reality TV show The Ultimate Fighter.
