KANSAS CITY, KAN. — Undefeated knockout artist Marco Romero (12-0, 11 KOs) continues to check every box as one of boxing’s most promising young prospects.
Nicknamed “El Tiburón,” the Kansas native has stopped 11 of his 12 opponents and has yet to lose a single round on the judges’ scorecards through 26 professional rounds. At just 20 years old, Romero combines devastating power with polish well beyond his years.
A 23-time U.S. national champion as an amateur, Romero compiled an eye-popping 130-5 record before turning professional. Since making his pro debut in 2019, the Olathe, Kansas product has steadily built momentum, blending ring IQ, charisma, and a relentless work ethic into what many view as the total package.
Built by Family, Guided by Experience
Romero’s development has been anything but accidental. His team, led by manager and trainer John Brown, has constructed a foundation rooted in discipline and long-term vision.
“Marco is a trainer’s dream because Marco and the team are all in it for the right reasons,” Romero’s manager/trainer John Brown commented. “Marco wants to be successful so he can help his family. He has great parents who have devoted their lives to their children. Marco is not the only ‘Star’ in the family as his younger brother is a highly decorated and recognized soccer prodigy. The parents have had no real life of their own devoting everything they have to the betterment of their athletic boys.
“Training Marco is a team effort with his father always there to give direction and guidance and the physical work is expertly conducted by two of my former amateur champions, Sergio Flores and Marcus Davidson. From my 65 years in the sport these two are the best trainers I have ever witnessed and Marco is blessed to have them. Complimenting the above is the addition of Dr. Tom Virgets, who is an exercise physiologist who helped me train Tommy Morrison to the heavyweight championship of the world. Dr. Virgets works closely with our strength and conditioning trainer, Chris Calovich.
“Outside the gym and a vital part of our team is the legendary Al Valenti, who has a lifetime of expertise in the marketing and promotion of boxers. Al was a driving force behind the success of Marvin Hagler, Micky Ward and many others. The business of pro boxing is a complicated web that Al helps clarify on an almost daily basis.”
With such a seasoned support system, Romero’s rise appears carefully calculated.
Statement Win in Florida
Romero’s latest performance came February 19 in the Orlando area, where he competed on the “Champions Against Domestic Violence” card promoted by Hall of Famer Christy Martin.
Facing late replacement Vaughn Alexander (19-18-2, 12 KOs), a seasoned veteran who has shared the ring with several world-class contenders, Romero adjusted seamlessly. Despite the opponent switch, he dominated the action, winning the first five rounds on all scorecards before closing the show at the end of round six with sharp, punishing combinations.
“My opponent was changed late but it didn’t affect me at all,” Romero said. “I still went out and got the job done, needing to do some minor adjustments. It was amazing to fight on a card promoted by Christy Martin. And, of course, who wouldn’t want to be in Orlando? Overall, it was an amazing experience.”
The bout marked the first time Romero extended beyond four rounds — and he passed that test emphatically.
No Time Off: Headlining March 20
Romero won’t be slowing down anytime soon. He returns to headline a March 20 card in Independence, Missouri, where he’ll face William Langston (14-5-1, 9 KOs) in an eight-round contest.
“I was back training the day after my last fight,” Romero noted. “Right back in the gym since I got back home. No time for breaks. We have a pretty good challenge ahead of us March 20th. We will be prepared for anything!”
Primarily competing at super middleweight, Romero is targeting a move down to middleweight by year’s end. With power, pedigree, and a disciplined team behind him, “El Tiburón” appears poised to make serious waves in 2026.
