About Sarah O'Brien

Sarah started her CrossFit career in 2022, while living in New England. With a background in strength training and track and field, she sought a new challenge and discovered CrossFit in her search! As a very social and competitive individual, CrossFit satisfied that need in a way that a regular global gym could not. She joined our CFEN community after moving to Nashville in 2024.

With a background in coaching youth sports and nine months of coaching at a functional fitness gym, pursuing her CrossFit L1 certification was a no-brainer. Though new to our coaching staff, she is already known for her big personality and the passion she brings to her classes. She is committed to ensuring that every athlete feels welcomed in class and supported in reaching their goals.

When she isn’t training and coaching CrossFit at CFEN, she competes in Strongman competitions, and spends time with her husband and her dog.
