MEET OUR TEAM

Jeff Saibil, a leading expert in biomechanics, rehabilitation, and performance optimization with over two decades of hands-on experience. A former Division 1 hockey player with a B.Sc. in Kinesiology, Jeff has built his career at the intersection of science, sport, and recovery.

 

The system was founded by Jeff in Montreal, where years of hard work, real-world testing, and relentless refinement shaped a method designed to solve pain at its root. The results spoke for themselves—transforming how clients moved, felt, and performed. The system’s success led to its international expansion, officially launching as Zone 4 Performance in Switzerland. It was quickly adopted by some of the country’s top physiotherapists and Olympic-level professionals for its ability to deliver elite-level outcomes.

 

Now based back in Montreal, Jeff brings the proven methodology of Z4P to a broader audience through Z4Pmtl—a facility and system built to guide people out of pain and into peak performance. Whether working with elite athletes or everyday movers, Jeff’s mission remains the same: deliver precise, personalized solutions that restore function, build strength, and transform lives—one movement at a time.
