  • Justin is very professional and always willing to work with the client dynamically as he adapts and modifies goals, even during a workout, so that his clients come away having done the absolute best for themselves physically. Great trainer, and he knows his stuff.

  • Justin listened to my needs and areas I wanted to work on. He was patient and explained the process every step of the way. I left my session mot only with a great workout but knowing more about how to accomplish my goals! I look forward to our sessions. Highly recommend!

    Stephanie E.

  • I worked with Justin for more than a decade. He respected my abilities as an older client, and with his knowledge and experience, he pushed me. When I quickly learned that I could trust his judgment, I then started to push myself. I would still be working with him if he had not moved out of state. I recommended him enthusiastically. Every session was productive and fun.
