The people behind your care

Meet our founder, Sara Arnold

ms, rd, cssd, ld, ceds, acsm-cpt

Sara created KC Performance Nutrition because she wanted to help athletes like her. KCPN is built on both clinical expertise and lived experience. Her 10-year battle with bulimia nervosa as an athlete shaped how she practices today. Health At Every Size® principles play an important role in how nutrition interventions are delivered at KC Performance Nutrition.

Sara is looked to as an expert in her field by many local organizations and professionals. She now primarily supports athletes with eating disorders and has a passion to help everyone achieve recovery and maintain their ability to move their bodies in a way that feels good.

Sara was featured in Voyage KC Magazine's 'Kansas City's Most Inspiring Stories'. Read more about about her story here.

Meet Haley Wilson

rd, cssd, ld, cscs

Haley is both a sports dietitian and certified intuitive eating counselor. As a former collegiate athlete, so much of her life revolved around performance, achievement, and the way her body looked. What started as a drive to succeed slowly turned into struggles with food and movement that left her feeling disconnected from herself. After finding intuitive eating herself, she enjoys helping athletes break free from rigid food rules and rebuild trust with their bodies.
‍
Her passion is helping others not only find freedom with food, but also to learn how to fuel in a way that supports performance, recovery, and long-term health. She believes movement should feel empowering, food should feel nourishing, and all bodies should be treated with kindness.
