Dan Severn is a pioneering figure in combat sports, known for his dominance in both mixed martial arts and professional wrestling. Since his high school days in Coldwater, Michigan, Severn built his athletic foundation as an accomplished amateur wrestler, earning All-American honors at Arizona State University. He rose to prominence in the early days of the Ultimate Fighting Championship, where his grappling-heavy style and physical strength earned him the nickname, "The Beast." Severn became a two-time UFC tournament champion and later captured the UFC Superfight Championship, helping lay the foundations for the sport during its formative years with his disciplined, wrestling-based approach.

Beyond MMA, Severn achieved notable success in professional wrestling, becoming a rare athlete to bridge the gap between "the octagon" and "the squared circle". He held the NWA Worlds Heavyweight Championship for over four years, one of the longest reigns in the title's history, and also competed in WWE during the late 1990s. Known for maintaining his amateur wrestling persona, Severn brought a unique authenticity to pro wrestling, rarely straying from his real-life fighting style. With a career spanning decades and a legacy rooted in toughness, versatility, and credibility, Severn remains one of the most respected figures in combat sports history.

From his home base in Arizona, Dan continues to help athletes of all ages and stays busy assisting others to reach their goals. To reach him regarding training or other ventures, he can be emailed at dan@dansevern.com.
