Jason Lee – Underground Fighter | K.O.T.S. Champion | Professional Mixed Martial Artist
Jason Lee is a fierce competitor born from hardship and shaped by resilience. Raised in a turbulent family environment, Jason’s early life took him through the rough neighborhoods of Charlestown and Lawrence, Massachusetts—places where struggle was part of the daily routine. Despite the chaos around him, Jason stood out as a gifted athlete, driven by a mantra he still lives by: “Ignore the pain, make the play.” At age 12, tragedy struck when he lost his older brother in a motorcycle accident. The loss shattered him, sending his life into a downward spiral that eventually led to a hard eight-year sentence in Colorado’s state prison system—an experience he refers to as “gladiator school.” But prison didn’t break Jason—it forged him. Upon release, he emerged as a changed man, both mentally and physically, committed to leaving his past behind. The one thing he carried with him was his passion for combat. Recognizing his natural talent and the discipline he’d developed behind bars, Jason redirected his energy into something positive: mixed martial arts. Jason then took fighting to the next level as a 2 Colorado State Champ Amateur, Sparta Undefeated Light Heavyweight World Champion, 2010 Colorado Fighter of the Year, 2015 Colorado Muay Thai Fighter of the Year, In 2024 Jason was inducted in the Sparta Sports and ENT Hall of Fame. Now a known force in the underground fighting circuit and a standout in King of the Streets (K.O.T.S.), Jason “The Dragon” Lee channels his past into every fight—fueled by grit, sharpened by pain, and driven by purpose. Tune in as Jason Lee joins Bobby Marshall in studio to discuss K.O.T.S. (King of The Streets), underground fighting, MMA, bare knuckle fighting, kickboxing, prison, parenting, street smarts, wildlife, Colorado, and much more.
