Was Joe Rogan once an MMA fighter?

Dana White was not an MMA fighter.. He was actually an amateur boxer.. kinda ironic. As for Joe Rogan, he started training in martial arts at the age of 13. He went on to become the "Machusetts full contact Tae Kwon Do champion" for four years in a row. By age 19, he won the US Open Tae Kwon Do championship as a lightweight, and went on to beat the middleweight and heavyweight champions to become the Grand Champion. Obviously he had a black-belt.
