Jonathan founded Ten Fld NYC in 2025 after more than a decade coaching athletes and high performers across New York City. He holds a Master's in Human Performance and is a Certified Strength and Conditioning Specialist (CSCS) through the NSCA, the gold standard credential in the field. His approach blends sports science, strength and conditioning, and corrective exercise. Every program is built around assessment first, periodized progressions, and the kind of attention to detail you only get from a private studio. No filler. No fluff. Alongside this, he ran strength training programs within a physical therapy clinic, helping clients transition from rehab back into full performance. This experience shaped a system that prioritizes movement quality, long-term progression, and individualized programming. Jonathan has worked with Broadway performers, broadcast journalists, executives, parents returning to training, and clients managing Parkinson's, MS, and other special considerations. The throughline is always the same: measurable progress, sustainable habits, and a coach who actually pays attention. Featured in Everyday Health
