Brian Welch was born in Torrance, California, on June 19th, 1970.

Brian and Munky went to the same school where Brian showed Munky how to play a few songs. They were friends up through high school, and had a friendly sort of competition with each other. Brian would go to Munky's house and jam. If Munky would learn some new material, Brian would be like, "d*mn I got to practice!". Later, Munky joined LAPD, while Brian would just sit around drinking their beer. LAPD decided that they needed a second guitar for when they toured, so Brian went on tour with them. Brian and Munky have been playing together for more than two thirds of their lives.
 

Brian's wife is Rebekkah, who recently gave birth to their daughter Jennea Marie, on July 6, 1998. As a result of the birth, Korn had to drop out of the 1998 OzzFest in Europe. Brian would not travel overseas and be away from his wife at such a crucial time, and the rest of Korn were set in the fact that they would not use any replacement musicians in any situation if one of them couldn't be on hand due to an extenuating circumstance.

When asked how he got the nickname "Head", Brian said: "...Because I got a big head... Go get me any hat, and it won't fit.
