With a background in physical therapy and over 15 years of hands-on experience working with thousands of clients from professional athletes to everyday individuals, I’ve built MKX Coaching to bridge the gap between science-based training, advanced nutrition, and sustainable lifestyle changes My career began in the world of physical therapy, where I developed a deep understanding of how the body moves, heals, and performs at its best. Over the years, I’ve had the privilege of working with elite athletes across various sports, helping them optimize performance, recover smarter, and build strength without sacrificing longevity. I hold advanced certifications in both strength training and nutrition, and I bring that knowledge into every program I design – whether your goal is fat loss, muscle gain, improved mobility, or peak performance.
