Carlos Kremer, known to fight fans around the world as “The Roaring Lion,” is one of the most electrifying voices in combat sports. His unmistakable growl and commanding presence inside the cage have made him a fan favorite as a ring announcer. But behind the booming voice and high-octane persona is a man grounded by love, family, and purpose.
In the world of MMA, Kremer’s name is synonymous with passion and professionalism. From his days as a decorated Marine to becoming the voice of BRAVE Combat Federation and other top-tier promotions, Carlos has built a reputation as a larger-than-life figure. Yet, ask him what his most important role is, and he won’t hesitate: it’s being a father and a husband.
A Warrior at Home
“I’m blessed to be called ‘The Roaring Lion’ in the cage,” Kremer says, “but at home, I’m just Dad to my kids and I make sure I coach them, workout with them and go to every game and practice I can while at home and try to be the best Partner I can be.”

Balancing the adrenaline-fueled chaos of international fight nights with family life isn’t easy. Between jet lag, rehearsals, and fight-week commitments, Kremer admits the schedule can be punishing. But he has developed a rhythm that keeps him grounded. “My wife and kids are my foundation. I may be halfway across the world on show night, but they’re always with me in spirit—and often on FaceTime backstage.”
Carlos credits his wife as the real MVP behind the scenes. “She holds it all together,” he says with admiration. “She’s the quiet strength in our family, always supportive, always encouraging me to chase this dream. I couldn’t do any of it without her.”

Discipline and Heart
Kremer’s ability to balance the demands of showbiz and family stems largely from his military background. A former U.S. Marine Corps Captain, he learned early on the values of structure, integrity, and discipline. Those lessons continue to shape how he manages time and handles pressure.

“The military taught me how to lead with passion and serve with purpose. I apply the same mindset to my work and my family. I give 100% to both.”
That work ethic has paid off. Whether he’s introducing world-class fighters to roaring crowds in Bahrain, South America, or Las Vegas, Kremer brings unmatched energy and presence. But when the mic is off and the tuxedo comes off, he seamlessly transitions into husband and dad mode—attending school plays, coaching youth sports, and celebrating family milestones.
More Than a Voice
While his booming announcements have become iconic, Carlos Kremer is more than just a voice in the cage. He’s a motivator, a mentor, and an example of how you can live boldly and still stay true to what matters most.
“My job is to help tell the story of the warriors who step into that cage. But at home, I’m part of a different kind of fight—the fight to be present, to love well, and to set an example for my kids about what it means to live with honor.”
As “The Roaring Lion” continues to dominate the announcing world, it’s clear his greatest achievements aren’t just measured in decibels, but in dedication—to the sport, to the fans, and most of all, to his family.
