My athletic background began with soccer early, soon after high school I transitioned into fitness. I decided to become a personal trainer because I wanted to help and educate the community about overall wellness, lifting, and provide guidance to achieve the desired goals of every population. My mission is to share my knowledge I gather in my own journey, continue to teach everyone about overall health, and establish positive relationships with exercise.

Hi y’all! I grew up in Austin, TX playing volleyball since I was 5 years old. I’ve always been active and passionate about wellness which led me to fall in love with various fitness activities from weight training to yoga. I’ve been able to see the various benefits that different forms of fitness have to offer, and my mission is to share the joy of physical activity with as many people as possible.

Born and raised ATL, GA. I played football at the college level for a year and dabbled in other sports while in high school. My dad introduced me to a gym at 7 years old and I just never left; my family owned a gym for a bit which gave me an early introduction to coaching. I believe my calling was to always coach as opposed to being the athlete myself. My greatest satisfaction is seeing a client/ athlete achieve goals they deemed impossible

My introduction into the fitness and exercise world came in the form of soccer. I have been playing soccer my whole life and I absolutely love it. Being a part of the University of Texas at Tyler soccer team showed me how important strength, conditioning, and speed training were when playing soccer. I then learned much more about the overall benefits of working out when I Interned at APEC and I saw firsthand the improvements made by individuals that were training there. I love the feedback I get from people about an exercise helping them in a way they didn’t think it could. I strive for more and in my time here I hope I can help clients and members improve their level of fitness and overall health.
