Chase Bruce, Coach
CF-L1 Trainer
Having an athletic background in baseball, Chase experienced a training program that mirrored the style of CrossFit back in 2016. 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. As a CF-L1 trainer, Chase’s number one goal is to push people to become the best they can be and assist them in the pursuit of their own goals.

Emily Gillis

Life looks better upside down if you ask Emily (aka E)! E began gymnastics at the age of 5 and hasn’t left the sport since. She competed at the University of Wisconsin-Whitewater and once her competitive gymnastics career ended, she started CrossFit and was instantly hooked! Emily manages/coaches full-time at Intrigue Athletics. After meeting Mike “Coach B” Burgener at the 2017 CrossFit Games, E began her journey as a competitive weightlifter under 1992 Olympian Osman Manzanares at Nashville Weightlifting Club. E loves using her platform (pun intended!) to inspire others and sharing what she learns from Coach Osman with our 3 Star members.


Mark Anderson, Coach
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. 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 for the Masters Division. Mark has successfully completed the USAW Level 1 Sport Performance coaches course, USAW Advanced Sport Performance course, and CrossFit Level 1 Trainer course. He’s always excited to coach CrossFit and weightlifting, but most importantly, to help others achieve goals they never thought possible. For the record, if you ever see Stevie G. beat Mark in a WOD, it’s because Mark let him!

Mike Edwards, Coach
CF-L1 Trainer
Mike would be 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.
