TJ De Santis joined Sherdog.com in December of 2005. Before moving to cover mixed martial arts, De Santis worked in the FM world for the better part of a decade. Starting at KXXR-FM (93X) in Minneapolis at the ripe age of 15, TJ moved to nights on the active rocker full time in 2006. De Santis melded his love of radio and MMA in 2004 when he started the "MMA Evolution" radio show. In 2007 TJ left the full time FM world to become the program director of the largest source for mixed martial arts, The Sherdog Radio Network.

TJ resides in Excelsior, Minn., just 25 miles west of Minneapolis. De Santis enjoys baseball, hunting, golfing, and video games. When not on-air, the radio personality spends time with his wife Melissa and son Oliver. He can also be heard on Minneapolis classic rock station 92KQRS.
