She, her husband Bryan, and their three girls moved to Wylie and she joined the CrossFit Wylie community in September 2014. In November, she received her Level 1 Certification in an effort to both enhance her knowledge of CrossFit but also to be able to coach and share her passion with others.

Jill knew when she retired from the military that she wanted to work with children in some type of physical fitness capacity to help them develop healthy lifestyles and to associate fitness as being fun early in life. As such, she decided to obtain her CF Kids Certification and is the head CF Kids coach for our gym. She loves what she does and it shows!
