Jason Fiorentino

Strength, Speed & Sports Performance Coach @ Kresson Sports

With over 20 years of experience in the gym and as a certified personal trainer, I specialize in strength, speed, agility, and conditioning for athletes of all ages, skill levels, and sports. I design fully customized training programs and arm care routines to meet the unique needs of every client—from youth athletes just starting out to competitive players looking to level up.

My approach is rooted in science-based training and nutrition—with no shortcuts. I build strong, capable athletes by focusing on the fundamentals first, prioritizing safety, proper technique, and long-term development. Whether it’s one-on-one coaching or high-energy group classes, I expect my clients to bring the same effort and commitment I do—and together, we get results the right way.

As a coach for the past 5+ years, I’ve led recreational, town, and travel baseball teams across three towns and two districts, helping young athletes grow not just on the field, but in confidence, discipline, and athletic IQ. As a proud father of four (ages 7–17), I understand how to connect with and motivate kids of all ages—and I treat every athlete I work with like they’re my own.

I’ve been part of Kresson Sports since day one, and I take extreme pride in my craft. I’m still actively training myself, staying athletically sharp so I can challenge my clients, demonstrate drills, and coach hands-on with energy and intention.

If you’re ready to train with purpose, develop real skills, and build a solid foundation for long-term success—I’m here to help you make it happen.
