Tiffany Wilkerson

Tiffany grew up in the mountains of Northwest Montana and spent her days hunting, camping, playing softball and traveling with her competitive jump rope team (she swears it’s a real thing). She went to college in Wisconsin where she not only earned her BS in Integrative and Medical Biology but also earned Conference Player of the Year in softball and a school record and Conference Championship in the 4×400 relay in track and field. In 2008 she was so bored of the classic treadmill run + weight room routine and went searching for her next fitness endeavor, she found CrossFit and never looked back. She believes anyone can do CrossFit and that the consistent CrossFitter will reach levels of fitness they didn’t think were possible. She is as excited to teach you how to air squat as she is to teach you how to muscle up. Tiffany spends her time wrestling her two boys, watching too much MMA with her husband and geeking out on bio-hacking.
