The Lion’s Den was founded in the early 1990s by UFC Hall of Famer Ken Shamrock, and since has been considered one of the most dominant fight camp’s in the early UFC era.

The Lion’s Den became highly successful for many years and was widely regarded as one of, if not the best, mixed martial arts schools in the world throughout the late 1990s and into the early 2000s.

Shamrock attracted the attention of American fighters Vernon White and Guy Mezger early on, and formed the first ever mixed martial arts team in the USA.

The Lions Den featured fighters such as Frank Shamrock, Jerry Bohlander, Tra Telligman, Pete Williams, and Mikey Burnett.
