Hi, I'm Justin. I've been a personal trainer since 2006. I am certified through NASM as a Performance Enhancement Specialist and through Functional Movement Systems as a FMS Level-1 expert. Having worked as a Physical Therapy technician back in 2007, I was introduced to corrective exercise, the process of assessing & treating clients, and the world of physical therapy as a whole. What started off as a challenge quickly became an incredibly rewarding experience. After moving on from the world of Physical Therapy, I started working as a trainer for a local health club. Since I began in the commercial fitness industry, I've met and worked with a wide variety of clientele ranging from 14 to 86 years of age. Having the opportunity to work with so many different individuals continues to be a wonderful experience for me. Whether the person is looking to lose bodyfat and "tone up", improve their sports performance, or is in need of guidance after finishing a rehabilitation program; I've always enjoyed seeing people exceed their own expectations. My training philosophy is simple. Do what works, and do it well!
