Dr. Aaron Armetta


Dr. Aaron graduated from Wheaton College in IL in 2003.  During his time at Wheaton, he received a three year Army ROTC scholarship and participated in football and wrestling for the Thunder.  Dr. Armetta commissioned as a 2LT in the United States Army in May of 2003 and served five years on Active Duty, including two combat tours to Iraq as a Medical Service Officer.  Following Active Duty Service, he chose to attend Logan College of Chiropractic in Chesterfield, Missouri.  He also received his acupuncture certification through the college and is certified and proficient in Active Release Technique, Graston soft tissue technique, and Kinesio taping.  Shortly after graduation from the Doctor of Chiropractic program, Dr. Armetta earned his Masters Degree in Sports Rehabilitation. He is also a Certified Strength and Conditioning Specialist (C.S.C.S.). He now works for Brodwyn & Associates at Brodwyn Military Chiropractic near Ft. Benning, after owning and operating a private practice in Illinois for two years.  Dr. Aaron is Crossfit Level I and has been coaching since 2013. He and his wife, Brittany, who is an athlete at Sacrifice, were married in April of 2014 and live in Columbus with their Dog, Lola.  They also recently found out Brittany is expecting in October of 2015!!  Brittany works as a mental health technician at St Francis Hospital – the Bradley Center.

I love Crossfit for so many reasons that it’s hard to condense it into a few paragraphs.  As a Doctor and Strength and Conditioning Coach / Personal Trainer, I know Crossfit is the most efficient and effective form of exercise in existence (when done with proper coaching, programming and without sacrificing form).  It is the only thing since college athletics that has been able to quench my competitive thirst.  It is a daily challenge for athletes of all ages and all skill levels.  The community of Crossfit offers a group of people who love each other, support each other and see eye to eye, sharing their love for this sport.  Although you can measure your scores against other athletes on Wodify, in the end, you are competing against yourself – to find out how hard you can push yourself, how far you can go, and just to be better.  I love coaching because it allows me to use my education and knowledge to assist athletes in achieving their goals and finding their limits in a safe and effective manner.  I don’t even call being one of Crossfit’s coaches a second job, because it doesn’t feel like work – it’s more like fun.

I love Crossfit because everyday is a new challenge, and anyone can do it. Crossfit makes people physically and mentally stronger!
I’m very passionate about fitness & helping others achieve their goals no matter how big or small. I learn from the athletes daily and I love the community.

Being a coach has been a great experience. Watching athletes develop over the course of time provides motivation and inspiration for me daily. I love helping athletes realize that they are capable of doing much more then then think they can do. I can provide the’ the tools to help get them where they want to be.

I was born and raised in Buffalo, New York. I’ve been doing Crossfit for 2 years but always been involved in sports and fitness. I was on the Track Team in High School as well as the Filed Hockey Team. I’ve done it all from Yoga, to Spinning, to Mud Runs, & currently Weight Lifting. I studied Physical Education and Health at Cortland State during undergraduate. For my Masters I studied Health and Human Performance
with a concentration in Strength and Conditioning Coaching at Canisius College.

My certifications include; Crossift Level 1 and USA Weightlifting Level 1. I also attended Carl Paoli’s Freestyle Connection Movement Seminar.

Go Bills!





Chris Snipes


Hello, I’m Chris. I’m from North Carolina. I was a distance runner for many years and came to CrossFit because I was looking to improve my overall fitness. I was an accomplished marathoner and ultra distance runner and I expected CrossFit to be an easy skill to pick up. I was surprised by how little functional fitness I had. Running alone wasn’t providing me with what I need to be a successful athlete or excel as a Soldier.

I enjoy teaching people about what CrossFit is and how it can improve anyone’s life. Whether you’re an accomplished athlete in a specific sport, a high tempo elite military operator, or a stay at home mom trying to keep up with your kids; CrossFit will improve your fitness and your life. I also love watching athletes develop friendships within our community. The community is probably one of the best side benefits of CrossFit.

I wrestled in high school and started running seriously in my early twenties. I enlisted in the U.S. Army at the age of 32 and served 8 years at Fort Benning, GA. I still serve in the Army Reserves. After leaving active duty, I began a career in law enforcement.

I’ve completed the CrossFit Level I certificate and have also attended the Jon North Attitude Nation Olympic Lifting seminar.

I found out about CrossFit in 2007 while attending college at Georgia Southern University. I was hooked. In the gym on campus, I did CrossFit style workouts on my own and after graduating in 2009 with a bachelors degree in exercise science, I moved to Columbus, GA and joined CrossFit Inception. In 2010 I pursued my CrossFit L-1 and shortly after started coaching. It’s been an awesome journey constantly trying to better myself as well as other athletes since then. Along the way, I’ve attended several seminars and achieved certifications including CF mobility training, Attitude Nation olympic lifting L-1 as well as becoming Eta Sigma Gamma National honorary in the field of health studies. I’ve got a strong passion for the sport of CrossFit and a stronger passion for the community CrossFit builds within a gym. I look forward to the future of CrossFit and will long continue down this road CrossFit has paved for me.
