I’ve been fortunate to call Dave a friend, teammate, training partner, coach, and mentor. Over the years, I’ve trained with people from many different systems, and I can honestly say that DZMMA Performance stands apart. This isn’t a collection of techniques or flashy social media moves. It’s a complete, battle-tested system built on what actually works—whether your goal is competition, self-defense, or becoming a more capable human being. Every lesson is grounded in experience, pressure-tested, and refined over decades. For more than 26 years, Dave has dedicated his life to learning from some of the greatest martial artists and coaches in the world. He didn’t just accumulate knowledge—he forged it into a philosophy. DZMMA Performance isn’t just about creating better fighters; it’s about developing discipline, resilience, confidence, and human optimization. Malcolm Gladwell wrote in Outliers that mastery requires roughly 10,000 hours of deliberate practice. If that’s true, then Dave is a Fucking Master several times over. But what impresses me most isn’t the hours—it’s his willingness to keep learning, keep evolving, and keep sharing that knowledge with everyone who walks through his doors. Great coaches teach techniques. Exceptional coaches change lives. Thank you, brother, for everything you’ve invested in all of us. OSS. 👊
