Our founder

Corey Lewis

Corey began training athletes in 2007 and in the summer of 2011, he began exploring the idea of opening his own facility in order to provide the best training facility for all of his athletes. After many months of hard work, CrossFit Xtra Mile opened on January, 9 2012. Since that day, Corey has stayed focused and never lost the desire to help people reach their goals. Corey gets enjoyment out of pushing people to be the best they can be and watching those people do things they never thought possible. Corey strongly believes that through Coaching and the amazing community at Xtra Mile Fitness that anything is possible. The human body can do amazing things if given the tools to do so and Corey looks forward to helping many more people over the years utilize those tools to reach their goals. One of Corey’s favorite quotes is, “A hard worker will eventually succeed,” and Corey strongly believes that!

Brad Jokerst coach at Xtra Mile Fitness

Brad Jokerst


Brad found CrossFit in 2010 after returning home from a trip to Hawaii. The surfing, and soreness that ensued, made him realize that he wasn’t quite as fit as he thought he was. He found CrossFit South City and was immediately obsessed. He would be a member and coach at the gym for nearly seven years. During this time, he found a renewed sense of competition and has competed in numerous regional events, including placing third at HOA in 2011. It was through CrossFit that Brad found his inspiration to become a firefighter and paramedic. He spent his first years in the fire service at The City of St. Charles Fire Department. He now proudly serves and protects the citizens of Xtra Mile’s community as a Firefighter/Paramedic for the Fenton Fire District.

Candace Bourisaw coach at Xtra Mile Fitness

It wasn’t until October of 2013 when Candace discovered and fell in love with Crossfit. Six months into her new found hobby, she competed in her first Individual competition and since has competed in a handful more of individual, couplet, and team competitions. As the years went by, Candace continued to enjoy the time she spent in the gym and started to get the idea of becoming a coach. It was then in March of 2019 when the opportunity came knocking on her door, and took part interning with Xtra Mile Fitness where she then studied and interned with some of the best Coaches in the St. Louis area. In May of 2019 she received her L1 and started solo coaching a few months later. She has enjoyed every minute of coaching new and veteran athletes, pushing them to their limits and seeing the excitement come across their face when they’ve hit a new lifting PR, or just got their first pull-up, or ran an entire 400m without stopping. Candace looks forward to the months and years to come, as she continues to grow personally as an athlete and as a coach here at Xtra Mile Fitness.

Abram Whitehead coach at Xtra Mile Fitness

Abram Whitehead


Abram was introduced to CrossFit in 2016. He often recounts walking through the doors with wide eyes and the intimidation of what he had heard about CrossFit. Like many, he was overweight, had poor mobility, limited skills and strength, and not the best self image. What he found was a coaching staff that was invested in his success and a community that was supportive, caring, and knowledgeable. It was everything he needed to call Xtra Mile home. Through his time at Xtra Mile, Abram has advanced every aspect of his fitness, competed in multiple events, and even became a USA Weightlifting Masters National Champion. Abram attained his CrossFit Level 1 certification so that he could bring his passion of life and fitness to others so that they might find their own personal growth. In this critical role of education, support, and encouragement, Abram always brings his unique blend of passion, performance ,and making fitness safe and fun!

Marco Mejia

Coach and Nutrition Coach

Marco was introduced to CrossFit in the summer of 2012 in preparation for his final year of collegiate baseball at St. Louis University. After completing his baseball career at SLU, his fitness journey began in competitive powerlifting, where he competed multiple times in the Midwest. Although lifting heavy was fun, he craved returning to training as a well-rounded athlete that could handle a variety of physical activities competently, which is what drew him back to training consistently in CrossFit at the end of 2017. He believes that physical fitness, in general, is a way to push yourself to places you didn’t think were possible before, and that will trickle out to have a positive effect on other aspects of your life outside of the gym. His draw to coaching is in finding the best methods possible to help athletes break through those new barriers and believe that they can continue on that path to achieve their goals.

Brenden Platt


In 2011, Brenden graduated college from Missouri State University with a BS in Kinesiology. During this time, he completed a 210-hour internship at Crossfit Springfield. It was during this experience that he realized his passion for helping improve the health, fitness, and wellness of others. Brenden believes the best investment you can ever make is in your own health. Crossfit provides a wonderful, unique experience and opportunity that allows individuals with all backgrounds the chance for their own personal investment in a fun, engaging way. Accumulating over a decade of hands-on experience and coaching hundreds of classes has allowed him to specialize in group fitness training, exercise prescription, fitness assessments, and weightlifting. As a coach, his goal is to ensure that members leave the gym feeling empowered and more knowledgeable than when they walked in. One of his favorite proverbs is – ‘Give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime.’ It is more worthwhile to teach someone to do something for themselves than to do it for them.

Brittany Lewis

Coach and Nutrition Coach

Dan Adler


Daniel started at CrossFit South City 9 years ago when a friend of his recommended he give it a try based on his fitness and health goals. Starting at a very young age, Daniel has been involved in some form of competition. Currently, he still competes in open-wheel dirt auto racing, which he finds CrossFit helps immensely from a conditioning standpoint. Beyond the competition aspect of CrossFit, Daniel believes the two major factors that have kept him involved for so long: functional fitness and community. He has seen how beneficial CrossFit has been in his life, along with so many others. CrossFit showed Daniel your fitness journey doesn’t have to be an individual one. He’s been motivated by coaches and other members throughout the years, which inspired him to to get his certification in 2019 when the opportunity became available. Daniel has enjoyed coaching new and veteran athletes ever since then, helping motivate and guide others to reach their own personal goals.
