Mary Guzman — Head Coach

Mary Guzman’s athletic journey began with gymnastics before she found her stride in swimming, eventually earning a spot as a sprinter on the University of Wisconsin–Madison swim team. After college, Mary balanced career and family life while staying active through Masters swimming, weightlifting, and running. In 2015, she was introduced to CrossFit by her husband, Erick—and quickly discovered a training methodology and community that resonated deeply with her competitive spirit and love of movement.

Mary joined the CrossFit Wilmette coaching team in 2022 and has since become a trusted, dedicated leader within the gym. As Head Coach, Mary supports and mentors the coaching staff while ensuring a consistently high-quality, positive class experience for all members. She remains committed to preserving each coach’s unique style while upholding CrossFit Wilmette’s standards of excellence. Mary continues to coach classes and work directly with athletes on the floor.

Professionally, Mary began her career as an engineer before transitioning into law, where she spent 19 years as a litigator at a major Chicago firm before joining Baxter Healthcare. After taking early retirement, she chose to focus on the pursuits she loves most—coaching at the top of that list. Mary is especially passionate about helping athletes move better, gain confidence, and become more efficient in their training.

Mary lives in Niles with Erick and their two dogs, Pepper and Kato, and proudly cheers on their children from afar.
