I’m Diego “Cut-Throat” Cortez, a Texas-born combat sports athlete, strength & conditioning coach, and owner of Havoc Athletics. I’ve been immersed in Muay Thai and strength training since I was 13, beginning as a middle schooler seeking confidence, self-defense skills, and a challenge. What started as curiosity quickly became a passion, and that passion has grown into a lifelong journey of excellence, both in the ring and beyond.

Over the years, I’ve built an undefeated amateur Muay Thai record, earning multiple national and international titles, including:

• Youth Texas State Champion

• USMTO Champion

• US Muay Thai Open Champion

• TBA Champion

• WBC Southwest Regional Champion

• WBC National Amateur Middleweight Champion

• Winner of the 1st WBC Muay Thai International Convention

I’ve also represented Team USA on the international stage, competing against some of the world’s best fighters. These accomplishments reflect not just talent, but relentless discipline, work ethic, and consistency—qualities that extend to my brand, my coaching, and my partnerships.
