Our Coaches

Chelsye Quinn

I grew up in Plymouth, in sports fueled family with two competitive older brothers pushed me from a young age to always be the best. This drive fueled me to beg my parents to drive me to the gym  and compete on the soccer field at the varsity level.  After college, when I received my associates degree in business and a licensed dental assistant, I began to look for that same drive that fueled me when I was younger and took a chance on CrossFit.  What I expected when I joined CrossFit was to get in better physical shape.  Those first few months were some of the most intense hardest workouts of my entire life. However, within four months I came in first place in my very first competition.  I was in peak physical shape, and what I failed to realize was how much it changed my mental shape. When I joined I did not realize the community this sport builds and continues to build.  I have made lifelong friendships inside these doors and those people don’t just push me to be a better athlete, they push me to be a better person.  As a coach, I will make sure that anyone who walks through that door grows not only physically, but mentally.   This gym builds bodies, molds minds, and strengthens spirits.

James Giles

Although powerlifting started as a way of keeping James out of trouble in his teenage years, his relationship to the sport quickly flourished into what has become a lifelong passion. In 2012, after several recommendations from friends over a short period of time, James was compelled to try out CrossFit. He began at BayState CrossFit with Tim and completed his first WOD (the filthy fifty), after which he remembered thinking, “That just kicked my ass!” Immediately, he was hooked. 


By 2013, after a year of CrossFit, James had begun expanding his knowledge and earned his CF-L1. The next hurdle, however, was far more daunting—coaching. With an incredible fear of public speaking, James struggled to imagine himself as the leader of a class. It was by far his greatest challenge since first being introduced to CrossFit. Encouraged by the strong CrossFit community and the mental fortitude that the sport builds—two things James cites as his favorite aspects of CrossFit—he worked hard to overcome his fear and joined the staff at BayState CrossFit.

He is extremely grateful for the opportunity to become an owner at BayState CrossFit and looks looking forward to helping people make positive changes in their lives one WOD at a time.

Outside the gym, James can be found operating heavy equipment, listening to podcasts, and spending time with Amanda and their children.
