Hannah O’Brien
Founder & CEO
As a lifelong athlete and coach, I have a passion for movement, competition, and helping others push past their limits. I was a three-sport varsity athlete at Colby College, where I played Field Hockey, Ice Hockey, and Lacrosse. During my time there, I had the opportunity to compete in multiple NESCAC tournaments, win a NESCAC championship, and play in an NCAA tournament game—experiences that shaped how I approach training, teamwork, and resilience.
After college, I shifted my focus to endurance running. When I turned 25, I completed a personal goal to run 25 races that year. I’ve finished two marathons and learned a lot about discipline, mental toughness, and how to train with purpose.
Over the past six years, I’ve gotten deeper into Olympic lifting and multi-modal training. I love combining strength, power, and conditioning in ways that challenge both the body and mind.
For 15 years, I’ve coached athletes of all ages across a range of sports. Whether I’m working with beginners or seasoned competitors, my goal is always the same: to help people become more confident, capable, and connected to their training.
