CF-L2 Trainer / CrossFit Judge / Rogue Fitness Judge

Widely known for his ability to consume large quantities of both brisket and little chocolate donuts (not at the same time), Joe also has a serious passion for helping people achieve. To quote Joe, “One of the greatest things in the world is watching someone achieve something they never imagined they could do – because I know exactly what that feels like.” Joe has been CrossFitting since 2010 and freely admits to “failing repeatedly” on his personal journey to self-fulfillment and good health but takes great pride in demonstrating hard work. Lastly, he’s also credited for pioneering something called the “Circle of Fun” and figuring out ways to incorporate Nerf sniper rifles into workouts.

Kaley is the taller half of the “Gillis Girls.” While she considers weightlifting her strong suit, Kaley is also part of our gymnastics clinic staff.

Mike Edwards

CF-L1 Trainer

Mike is the taller/balder guy around the gym! He found himself in a CrossFit box for the first time in 2012 while in school at Tennessee Tech University. The way it made him feel made the sport an instant passion for him. The challenges and plethora of new things to learn were coming on daily basis. Successes in the gym were coming more frequently and from all aspects of fitness, and he quickly realized every WOD is an opportunity to achieve a goal. CrossFit was way better for Mike than lifting for 2 months to only see his bench max go up 5 lbs. He soon realized he wants everyone to feel the way that CrossFit makes him feel so he began coaching! Mike loves getting people started and staying on the right path toward meeting their fitness goals.

Emily Adams

CF-L1 Trainer / Gymnastics coach

Emily first started CrossFit in 2018 after retiring from competitive gymnastics. Unsure if anything would ever take its place, she quickly fell in love with the community and challenge that CrossFit provided her. After spending years coaching gymnastics, coaching CrossFit became a natural next step. Emily is a recent graduate of Belmont University earning her Bachelor’s degree in Health Science. She’s now working toward her Doctorate in Physical Therapy. Having recovered from multiple injuries herself, Emily is very passionate about educating others on safe and effective movement patterns.

Mark Anderson

CF-L1 Trainer / USA Weightlifting Advanced Sport Performance Coach

Mark has been doing CrossFit since April 2015. He was immediately hooked, not only because the sport challenged him every day, but also because of the positive atmosphere that surrounded him.

He is currently the USAW Tennessee State record holder for the Snatch and Clean & Jerk in his weight class and age division. Mark has successfully completed the USAW Level 1 Sport Performance coaches’ course, USAW Advanced Sport Performance course, and CrossFit Level 1 Trainer course.

Chase Bruce

He quickly realized the importance and impact of physical training and how it related to overall performance and well-being, both on and off the field. After graduating high school, he realized that the true passion he had was related to the preparation and training he had experienced through sport. He started CrossFit in 2017, and it has become a passion for him ever since. Chase is a college student working toward a Masters degree in Athletic Training and plans to use that as a platform for his future career. Whether it be in the gym or in life, Chase enjoys seeing people reach their goals and he appreciates the dedication, commitment, and hard work it takes to obtain them.
