CrossFit FIF Staff - Ownership and Coaches who know their members personally.


Chase Knight, Founder, Head Coach

I’ve been coaching in some capacity for the last 6 years.  My passion for fitness and CrossFit developed while in the Army and grew in Afghanistan as a volunteer coach for Coalition Forces in Kabul.  Attended the Level 1 course in February 2014 and the rest is history.  I opened CrossFit FIF on the simple aspect of being able to help others achieve their personal goals in life.  I’m a SGT in the Missouri Army National Guard.  I’m a husband, father to two beautiful boys, coach, and athlete.  And I love every minute of it.

Sarah Sauer, Owner, Coach

A good chunk of my life I’ve spent as a swimmer, dabbled in running and after completing a triathlon decided I wanted to get stronger.  That’s when I decided to try CrossFit and have been in love ever since. In March 2015, I got my Level 1 at NorCal CrossFit and in June 2015 got my first coaching position.  I opened CrossFit FIF because I want others to experience the same things that CrossFit has helped me grow in, mentally and physically.
