CF-L2 Trainer / Burgener Strength certified / The Gymnastics Course certified / CPR & AED certified

One of Mary’s favorite motivations as a coach is helping members break past the voice that says “I can’t” to help them discover anything is possible. She brings that passion to every class! Mary has a B.S. in Nutrition Science and began her professional career as a certified Personal Trainer and Speed & Conditioning Specialist, where she gained experience helping people of all ages, fitness levels, and abilities meet their health and fitness goals. She discovered CrossFit in 2017 after becoming a mom and needing a more family-friendly environment than conventional gyms offer. She quickly fell in love with the challenge and community CrossFit provides, and within a few months knew she wanted to coach because of the impact CrossFit had on herself – creating a shift in mentality from how her body looks to what it’s capable of. As an athlete, Mary enjoys competing (especially as a team) for the additional challenge of training for them. As a coach, she understands every one’s fitness journey is different and enjoys working with athletes of all levels – from the first-timer enthusiastic to begin to the seasoned athlete looking to fine-tune their performance.

Mike Edwards

CF-L2 Trainer / CPR & AED certified

Mike is the tall/bald 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.

Mark Anderson

U.S. Army Veteran / CF-L2 Trainer / USA Weightlifting Advanced Sport Performance Coach / CPR & AED certified

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. In April 2017, Mark made the decision to train exclusively with weightlifting and began competing. 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 2 Trainer course. He’s always excited to coach CrossFit and weightlifting, but most importantly, he’s excited to help others achieve goals they never thought were possible. For the record, if you ever see Stevie G. beat Mark in a WOD, it’s because Mark let him!


CF-L1 Trainer / CrossFit Masters Course certified / CPR & AED certified

Cara has been a member of 3 Star CrossFit for 4 years. Her passion for CrossFit began from watching her own mother start CrossFit and seeing how much it improved her quality of life at an age when traditionally a decline in activity and health could seem somewhat acceptable. Cara has completed the CrossFit Masters training course and now specializes in working with the “legends” of our generation (age 50 and up) helping them to gain/maintain strength, develop a healthier and more active lifestyle, and retain independence as we age. To learn more about our Legends Class, click here! Cara’s favorite aspect of CrossFit’s functional movements is their ability to transcend into our everyday life. She is a mother of two, a hobby farmer, a novice gardener, and nature lover. She enjoys backyard games of baseball with her family, hiking, fishing, and cooking.

Emily Adams

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.

Kellye Dykes

CF-L1 Trainer / Spot the Flaw Course Certificate / Teaching Movement Course certificate / CPR certified

After years of long-distance running and training for half marathons, a friend introduced Kellye to CrossFit, telling her it would improve her running times.
