About
Precision. Pressure. Progress.
At Gryffon Performance, we don’t believe in average.
We coach the driven—the entrepreneurs, leaders, and high performers who demand more from their bodies, minds, and lives.
Founded by David Gryffon, Gryffon Performance was built to fill a gap in the fitness industry: where aesthetics, strength, and mental toughness come together under one system.
We’re not just here to make you look better—we’re here to help you operate at your highest level, every single day.
Our approach blends elite strength and conditioning, performance nutrition, and lifestyle execution into a complete system for human optimization.
Whether you train in-person at our Dallas facility or remotely through our coaching app, you’re held to the same standard: honor, mastery, and integrity.
We don’t guess. We don’t wing it.
We track data, deliver outcomes, and train every client like an athlete—because your life demands it.
What We Stand For
Precision: Every program, macro, and movement is built with intent. No wasted effort.
Pressure: We coach you to perform under stress, not just in the gym—but in life.
Progress: Physical. Mental. Emotional. We measure what matters and move it forward.
Who We Work With
Gryffon Performance serves high performers across all fields—executives, business owners, creatives, athletes, and those ready to train with purpose. If you’re done coasting and want to operate with clarity, control, and execution—you belong here.
Where We Train
We’re based in Dallas, TX at Self Made Training Facility – 1925 E Levee St, Dallas, TX 75207, and coach clients across the country through our Gryffon Performance App.
Our Promise
We don’t just help you get in shape. We help you become the type of person who never falls out of it.
Dedicated to your Success,
