Meet Sara
MS | RD | CSSD | LD | CEDS | acsm-cpt
Hi, I'm Sara Arnold, the founder of KC Performance Nutrition. As a former athlete, I've felt the pressures to look and eat a certain way — often at the expense of my mental health. I know what it's like to tie your worth to your performance or your body, and how quickly food can become confusing and overwhelming. Through my own struggles with disordered eating and body image, my experience has shaped my entire philosophy as a dietitian.
KC Performance Nutrition isn't just a business — it’s a deeply personal passion project built on the values I wish I had access to as an athlete. It's my way of helping others fuel with confidence, rebuild trust with their bodies, and prioritize both performance and well-being without having to choose between the two. Every client I work with is a reminder of why I do this work. In helping others, I continue to heal my younger self because I've been where you are, and I believe you deserve better.
Sara is only accepting a few more new clients!

Meet Haley
RD | CSSD | LD | Cscs
Hi, I’m Haley Wilson, a Sports Dietitian and Certified Intuitive Eating Counselor! As a former collegiate athlete, so much of my life revolved around performance, achievement, and the way my body looked. My worth felt wrapped up in winning, in discipline, and in the constant pressure to push harder. What started as a drive to succeed slowly turned into struggles with food and movement that left me feeling disconnected from myself. Finding intuitive eating changed everything. It gave me the freedom to step away from the obsession and realize there was a way to feel like my best self without tying it to rigid rules or constant comparison. For the first time, I felt present—in my body, in my relationships, and in all the moments life has to offer.
Now, as both a dietitian and active mom, I get to walk alongside athletes and active individuals who are ready to rebuild trust with their bodies. My passion is helping others not only find freedom with food, but also learn how to fuel in a way that supports performance, recovery, and long-term health. I believe movement should feel empowering, food should feel nourishing, and your body deserves kindness along the way.
